Description

Mucosa forceps

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of mucosa forceps.

Background technology

Mucosa forceps is a kind of medical apparatus and instruments commonly used during nose section performs the operation, and pincers are got nasal mucosa usefulness when supplying the operation of nose section.

Present existing mucosa forceps comprises pincers handle of being made up of upper plier handle and lower plier handle and the binding clip of being made up of symmetrical oval upper grip head and oval lower pliers head, and upper plier handle and lower plier handle are rotatedly connected; Oval upper grip head and lower plier handle are fixedly linked, and oval lower pliers head and upper plier handle are fixedly linked; The inner surface (promptly facing the face of oval lower pliers head) of oval upper grip head and the inner surface (promptly facing the face of oval upper grip head) of oval lower pliers head are plate shaped.During actual the use,, control oval upper grip head, thereby accomplish the work of getting mucosa that clamps with oval lower pliers head is made relative open and close through handling the pincers handle.This mucosa forceps exists following defective: because the inner surface of oval upper grip head and the inner surface of oval lower pliers head are plate shaped; Therefore after the inner surface of the inner surface of oval upper grip head and oval lower pliers head was clamped nasal mucosa, needs firmly could be shut down nasal mucosa from nasal cavity.

Summary of the invention

The technical problem that this utility model will solve provides a kind of mucosa forceps that can easily nasal mucosa be removed from nasal cavity.

In order to solve the problems of the technologies described above; This utility model provides a kind of mucosa forceps; Comprise pincers handle of forming by upper plier handle and lower plier handle and the binding clip of forming by symmetrical oval upper grip head and oval lower pliers head; Upper plier handle and lower plier handle are rotatedly connected, and oval upper grip head and lower plier handle are fixedly linked, and oval lower pliers head and upper plier handle are fixedly linked; Inner surface at oval upper grip head is provided with oval upper groove, and the wall thickness of oval upper groove is 0.2～0.3mm; Inner surface setting and the symmetrical oval low groove of oval upper groove at oval lower pliers head.

Improvement as the mucosa forceps of this utility model: through hole is set in the bottom of oval upper groove; In oval upper groove around on through hole internal ring is set; The bottom of last internal ring and the bottom of oval upper groove are fixedly linked; The top of last internal ring is than the low 0.2～0.3mm in the top of oval upper groove, and the wall thickness of last internal ring is 0.5～0.6mm; Be provided with and the symmetrical lower through-hole of last through hole in the bottom of oval low groove, in oval low groove around lower through-hole setting and the symmetrical following internal ring of last internal ring.

The mucosa forceps of this utility model; Because the inner surface at oval upper grip head is provided with oval upper groove; Inner surface setting and the symmetrical oval low groove of oval upper groove at oval lower pliers head; And the wall thickness of oval upper groove is 0.2～0.3mm, and oval low groove is because symmetrical with oval upper groove, and therefore the wall thickness of oval low groove also is 0.2～0.3mm; Because the wall thickness of oval upper groove and oval low groove is all very thin, when oval upper grip head and oval lower pliers head were closed, oval upper groove and oval low groove can be sheared nasal mucosa get off as sharp shears easily.This utility model also is provided with internal ring in oval upper groove; The top that should go up internal ring is than the low 0.2～0.3mm in the top of oval upper groove; And in oval low groove, be provided with and the symmetrical following internal ring of last internal ring, therefore 0.2～0.3mm is hanged down than the top of oval low groove in the top of internal ring down; When oval upper grip head and oval lower pliers head closure, (this spacing is 0.4～0.6mm) to keep certain spacing between the top of the top of last internal ring and following internal ring; Nasal mucosa can be clamped between the top of top and following internal ring of internal ring, thereby guarantees that nasal mucosa can not drop at nasal cavity in shear history.Through hole can alleviate the weight of oval upper grip head in the setting of the bottom of oval upper groove, and in like manner, the lower through-hole that is provided with in the bottom of oval low groove can alleviate the weight of oval lower pliers head; Thereby be convenient to the medical worker mucosa forceps of this utility model is carried out valid function.

Fig. 4 is that Fig. 1 removes and overlooks the amplification partial schematic diagram behind oval upper grip head 1 and the lower plier handle 5.

The specific embodiment

Fig. 1～Fig. 4 combines to have provided a kind of mucosa forceps, comprises pincers handle of being made up of upper plier handle 4 and lower plier handle 5 and the binding clip of being made up of symmetrical oval upper grip head 1 and oval lower pliers head 2, and upper plier handle 4 is rotatedly connected through pincers arbor pin 3 with lower plier handle 5; Oval upper grip head 1 is fixedly linked with lower plier handle 5, and oval lower pliers head 2 is fixedly linked with upper plier handle 4; The same prior art of said structure, the also same prior art of its occupation mode.

Inner surface (promptly facing the face of oval lower pliers head 2) at oval upper grip head 1 is provided with oval upper groove 11, and the wall thickness of oval upper groove 11 is 0.2～0.3mm; At the inner surface (promptly facing the face of oval upper grip head 1) of oval lower pliers head 2 the oval low groove 21 symmetrical with oval upper groove 11 is set.

In the bottom of oval upper groove 11 through hole 12 is set; In oval upper groove 11 around on through hole 12 internal ring 13 is set; The bottom of the bottom of last internal ring 13 and oval upper groove 11 is fixedly linked; The top of last internal ring 13 is than the low 0.2～0.3mm in the top of oval upper groove 11, and the wall thickness of last internal ring 13 is 0.5～0.6mm.Last through hole 12 all can be selected oval shape with last internal ring 13.The lower through-hole 22 symmetrical with last through hole 12 is set in the bottom of oval low groove 21, oval low groove 21 in, is provided with and following internal ring 23 that last internal ring 13 is symmetrical around lower through-hole 22.

During actual the use; Oval upper grip head 1 is stretched into nasal cavity with oval lower pliers head 2; Through handling the pincers handle of forming by upper plier handle 4 and lower plier handle 5; Control oval upper grip head 1 and open relatively, make nasal mucosa between the inner surface of the inner surface of oval upper grip head 1 and oval lower pliers head 2 with oval lower pliers head 2.When oval upper grip head 1 and oval lower pliers head 2 were closed, nasal mucosa can be clamped between the top of top and following internal ring 23 of internal ring 13, thereby guarantees that nasal mucosa can not drop at nasal cavity in shear history; And this moment, closed oval upper groove 11 and oval low groove 21 are sheared nasal mucosa get off as sharp shears easily; Be sheared the nasal mucosa that gets off along with mucosa forceps is taken out of outside the nasal cavity.

At last, it is also to be noted that what more than enumerate only is a specific embodiment of this utility model.Obviously, this utility model is not limited to above embodiment, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of this utility model all should be thought the protection domain of this utility model.
