The embedding needle is the instrument the whole procedure depends on, and its critical dimension is the one nobody can see: the bore. It has to accept the thread without shaving or catching it, hold it through the insertion, and release it at the point. A bore that is a fraction too tight damages the thread as it passes; one that is too loose lets it drop early. Everything else about the needle — length, tip, handle — is secondary to that fit.

This category covers the embedding needle supplied on its own, for clinics and distributors who source the thread separately or who already have a thread specification to match. Needles are available in hollow and slotted body formats, with the length selected against the depth of the points treated, and are supplied sterile and single-use with the lot documentation the clinic's infection control requires.

Buyers in this category are usually making one of two decisions: which bore matches the thread they already standardised on, or which needle length covers their point protocol. Both are answerable with a specification rather than a sample-and-hope.

Already standardised on a thread and need the right needle bore? Send us the thread material and gauge. We will specify the bore that passes it cleanly, and send samples so you can run the pass before ordering stock.

Disposable Thread Embedding Needle in practice

Catgut embedding protocols — hollow-body needles matched to the thread in use
Weight management point protocols — standard lengths for body points
Chronic pain point embedding — needles for repeated point protocols
Facial and superficial point work — fine, shorter needles for shallow placement
Clinic stock replacement — needles supplied separately from thread where the clinic sources its own
Distributor stock lines — bore and length combinations held as a small standard range

Choosing the right Disposable Thread Embedding Needle

Two specifications settle the order:

Bore to thread gauge. The single most important pairing. Send the thread material and gauge, and the bore is specified against it rather than chosen approximately. A mismatched bore is the most common cause of threads that catch, fray or drop.
Length to point depth. Needle length is set by how deep the treated points sit and by how much shaft the practitioner wants outside the skin for control. This follows the protocol rather than a general preference.
Body format. Hollow-body and slotted designs suit different threads and handling preferences. Confirm which your technique uses, since they are not interchangeable in practice.
Where the thread comes from. If you source thread independently, confirm its gauge tolerance — a thread at the loose end of a wide tolerance band can behave differently from one at the tight end in the same needle bore.

Disposable Thread Embedding Needle specifications

Parameter	Typical options	Effect
Bore diameter	Matched to thread gauge	Determines whether the thread passes and holds
Body format	Hollow / slotted	Thread retention and release behaviour
Needle length	Short / standard / long	Placement depth and external control
Tip	Sharp, controlled geometry	Penetration and placement accuracy
Handle	Contoured grip	Control during insertion and release
Sterilization	EO, SAL 10⁻⁶	Single-use sterile supply

Note: bore is specified against your thread gauge; length is confirmed against the point protocol.

How we control quality for Disposable Thread Embedding Needle

Embedding needles are judged on bore quality and on sterility that removes reprocessing:

Bore surface and diameter. The internal bore is checked for surface finish and diameter so the thread passes without being shaved, and is retained until release.
Tip and shaft integrity. Tip geometry and shaft straightness are controlled and inspected at batch level — a needle that flexes unpredictably cannot place a thread accurately at depth.
Handle joint strength. The handle-to-shaft joint is tested so the needle does not rotate under the pressure of insertion.
Sterilization. EO sterilization to SAL 10⁻⁶ with residuals tested to ISO 10993-7, individually pouched with lot and expiry.
Biocompatibility. ISO 10993 testing for a needle in prolonged tissue contact, with handle and coating materials declared.
Traceability. Lot number links the needle to its production and sterilization batches, with a specimen traceability sheet available for your registration file.

Common questions about Disposable Thread Embedding Needle

How do I know which bore fits my thread gauge?

The bore is specified against the thread you use, so the answer comes from the thread specification rather than from a general size chart. Send us the thread material and gauge and we will confirm the corresponding bore. Getting this right is the difference between a thread that advances smoothly and one that catches, frays or drops before it reaches the point.

What needle length is used for body point embedding?

Length follows the depth of the points in your protocol and how much shaft the practitioner wants to keep outside the skin for control — most body points are served by a standard length, with longer needles reserved for deeper points and shorter, finer needles for facial and superficial work. Confirm your protocol and we will map it to a small number of lengths.

Are these needles compatible with any resorbable thread?

They are compatible with the thread gauge they are specified against. Because resorbable threads differ in material, stiffness and diameter tolerance, a needle matched to one thread may not pass another of nominally similar size as cleanly. If you use more than one thread type, tell us and we will confirm the bore for each rather than assuming one needle covers both.

What is the difference between hollow-body and slotted embedding needles?

A hollow-body needle carries the thread inside the bore through the procedure and releases it at the point; a slotted needle holds the thread along the shaft. They suit different threads and different practitioner preferences, so the choice follows the technique in use rather than being interchangeable.

Are the needles sterile and single use?

Yes. Needles are EO sterilized to SAL 10⁻⁶ and individually pouched with the lot number and expiry printed on the unit, supplied for single use. This removes the sterilization-validation burden that reusable embedding needles place on a clinic, and gives one traceable lot number per procedure.

Do you supply embedding needles under our own brand?

Yes. Needles are supplied with your artwork, part numbers and IFU, including the label content your market requires. Because the bore is matched to a specific thread, private-label needles are set up per configuration rather than as a single generic line.
