Description

Medical stainless steel elastic thread ligation clamp

Technical Field

The utility model belongs to a medical operation auxiliary instrument, in particular to a pair of medical stainless steel elastic thread loop ligature forceps.

Background

The principle of elastic thread ligation is to ligate a specially made rubber ring (such as rubber ring, latex ring, silica gel ring, etc.) at the root (or base) of the pathological tissue of a patient, so that the blood supply of the hemorrhoid is blocked by the elastic retraction force of the rubber ring, and the hemorrhoid is necrotized, atrophied and dropped off, thereby achieving the purpose of healing. The traditional apparatus used for carrying out the ligation operation is simple and crude, the operation is time-consuming and labor-consuming, and complications are easy to occur. To address this situation, a variety of ligation devices have been developed in recent years. Although the ligation instruments are simple, convenient, rapid and accurate to operate when used for performing the ligation operation; the operation can be completed by a single person, and the time consumption is short; the probability of complications is low, patients generally do not need anesthesia, the pain is slight, most patients do not need hospitalization, the treatment cost is low, and the like, but special ligation instruments are required to be manufactured, and the problems of complex structure, troublesome disinfection and the like still exist.

Disclosure of Invention

The utility model aims to provide a medical stainless steel elastic thread ligation clamp with reasonable structure, easy manufacture, simple operation and multiple functions for the market.

The technical scheme of the utility model is that: the left tong arm and the right tong arm are hinged into a whole through a pin shaft, a right tong mouth arranged at the front end of the left tong arm and a left tong mouth arranged at the front end of the right tong arm are both in a semi-cylindrical shape, the inner side clamping surfaces of the right tong mouth and the left tong mouth are both planes provided with tooth grooves, the two tong mouths are in a cylindrical shape when clamped, the front part of the left tong mouth is provided with a threading hole, and a threading head of the elastic coil penetrates through the threading hole arranged on the tong mouths and is sleeved on the left tong arm and the right tong arm. And a thread groove is arranged at the top end of the plier mouth at one side of the threading hole.

The utility model has the advantages that: the multifunctional medical instrument has the advantages of reasonable structure, easiness in manufacturing, simplicity in operation and the like, achieves the purpose of multiple purposes, can save a large amount of medical instrument expenses, can be widely applied to departments such as anus and intestine, gynecology, five sense organs, skin and the like, and has a very wide market prospect.

The present invention will be further described with reference to the accompanying drawings.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic view of the structure of the utility model in use.

In the figure: the left tong arm 1, the right tong arm 2, the left finger ring 3, the right finger ring 4, the left locking tooth 5, the right locking tooth 6, the pin shaft 7, the right tong nozzle 8, the left tong nozzle 9, the tooth socket 10, the wire casing 11, the wire threading hole 12 and the elastic coil 13.

Detailed Description

As shown in figure 1, the medical stainless steel elastic thread ligation forceps comprise a forceps arm, a finger ring, a lock tooth, a pin shaft, forceps nozzles, an elastic coil and the like, wherein a left forceps arm 1 and a right forceps arm 2 are hinged into a whole through a pin shaft 7, a right forceps nozzle 8 arranged at the front end of the left forceps arm 1 and a left forceps nozzle 9 arranged at the front end of the right forceps arm 2 are both in a semi-cylindrical shape, the inner side clamping surfaces of the right forceps nozzle 8 and the left forceps nozzle 9 are both planes provided with tooth spaces 10, the two forceps nozzles are in a cylindrical shape when clamped, a threading hole 12 is arranged at the front part of the left forceps nozzle 9, and a thread groove 11 is arranged at the top end of the forceps nozzle at the side provided with the threading hole 12. The thread pulling head of the elastic coil 13 passes through the threading hole 12 arranged on the forceps mouth and is sleeved on the left and right forceps arms. The tail ends of the left forceps arm 1 and the right forceps arm 2 are respectively provided with a left finger ring 3, a left locking tooth 5, a right finger ring 4 and a right locking tooth 6, so that in order to facilitate the elastic coil 13 to be pulled out and sleeved on a pulled-out pathological change tissue from a self-clamping cylindrical forceps mouth, the forceps mouth can be made into a shape that the front mouth tip is slightly smaller than the rear mouth body, and the forceps mouth is in a circular truncated cone shape. Implement the utility model discloses the time, the doctor of performing the operation at first wears out the head end of acting as go-between of stretch coil 13 in the through wires hole 12 of setting on left pincers mouth 9 according to actual need, then overlaps stretch coil 13 on left pincers mouth 9 and right pincers mouth 8, inserts the finger again and takes up the pliers in the finger circle, stretches into the pathological change tissue department that needs the operation with the pincers mouth and presss from both sides it, only needs to pull the head of acting as go-between that stretch coil 13 can slide stretch coil 13 from the pincers mouth to the pathological change tissue on and tighten it. The utility model can be widely applied to medical operation as common medical forceps, has the advantages of reasonable structure, easy manufacture, simple operation and the like, realizes the purpose of multiple purposes, and can be widely applied to departments such as anus and intestine, gynecology, five sense organs, skin and the like.
