Description

Grab firm biopsy forceps

[ technical field ] A method for producing a semiconductor device

The utility model relates to the technical field of medical instruments, in particular to the technical field of biopsy forceps which can firmly grasp.

[ background of the utility model ]

Endoscopy is becoming more widely used in clinical medical examinations as a method of assisting diagnosis. The biopsy forceps can extend into the body of a patient through an endoscopic forceps channel and clamp lesion tissues, and are indispensable tools for obtaining pathological specimens in endoscopy. Referring to fig. 1, the head of the conventional biopsy forceps is generally provided with two clamping plates a hinged to each other to form a scissors shape. However, since the tissue of the lesion site in the human body thoracic cavity is hard and slippery, the tissue is likely to slip out from between the two splints a during the clamping, which results in sampling failure.

Preferably, the forceps body main body comprises an operating handle, a guide pipe and a pull rope, the operating handle comprises a handle rod and a sliding sleeve, the top end of the handle rod is connected with the bottom end of the guide pipe, at least 3 forceps fingers are hinged to the top end of the guide pipe respectively, the sliding sleeve is connected to the outside of the handle rod in a sliding mode, the pull ropes penetrate through a channel in the guide pipe respectively, and the upper end and the lower end of the pull rope are connected with the forceps fingers and the sliding sleeve respectively.

Preferably, the bottom end of the handle rod is provided with a stopper.

Preferably, the stopper is annular.

Preferably, the binding clip comprises a support plate and binding fingers, the support plate is horizontally arranged at the top end of the guide pipe, and at least 3 binding fingers are respectively arranged at the edge of the support plate in a surrounding manner and hinged with the support plate.

Preferably, the top end of the clamp finger is provided with a sharp part.

Preferably, the clamp finger is crescent-shaped, the bottom end of the clamp finger is hinged with the edge of the support plate, and the top end of the pull rope is fixed with the middle-lower part of the inner side of the clamp finger.

Preferably, the top end of the pulling rope is arranged through the rope hole of the supporting plate.

The utility model has the beneficial effects that: the claw-shaped tong head with at least 3 tong fingers is arranged to replace the traditional scissor-shaped tong head, so that the grasping fastness of the biopsy forceps to human tissues is greatly improved, the biopsy forceps are prevented from being separated from the tong head, the success rate of sampling is effectively improved, the integral structure is simple, the preparation is simple and convenient, and the cost is low; the clamping fingers are arranged in a crescent shape, and the sharp part is arranged at the clamping end of the clamping fingers, so that the clamping of human tissues is further facilitated; through set up annular fender piece in the bottom of handle pole, can avoid the sliding sleeve to deviate from among the handle pole on the one hand, conveniently hang again and place.

The features and advantages of the present invention will be described in detail by embodiments in conjunction with the accompanying drawings.

FIG. 1 is a schematic head view of a prior art bioptome;

FIG. 2 is a front view of a bioptome of the present invention configured to securely grasp;

fig. 3 is an enlarged schematic view at a of fig. 2.

In the figure: 1-operating handle, 11-handle rod, 12-sliding sleeve, 13-blocking piece, 2-conduit, 3-tong head, 31-supporting plate, 32-tong finger, 321-sharp part, 4-pulling rope and a-clamping plate.

[ detailed description ] embodiments

Referring to fig. 1, 2 and 3, the biopsy forceps with firm grasping according to the present invention includes a forceps main body and a forceps head 3, where the forceps head 3 includes at least 3 forceps fingers 32, and the forceps main body controls the forceps fingers 32 to move close to or away from each other so as to grasp or release human tissue.

The clamp body main part comprises an operating handle 1, a guide pipe 2 and a pull rope 4, wherein the operating handle 1 comprises a handle rod 11 and a sliding sleeve 12, the top end of the handle rod 11 is connected with the bottom end of the guide pipe 2, at least 3 clamp fingers 32 are respectively hinged to the top end of the guide pipe 2, the sliding sleeve 12 is slidably connected outside the handle rod 11, the pull ropes 4 are respectively arranged in an in-pipe channel of the guide pipe 2 in a penetrating mode, and the upper end and the lower end of the pull rope 4 are respectively connected with the clamp fingers 32 and the sliding sleeve 12.

The bottom end of the handle 11 is provided with a stopper 13.

The stopper 13 is annular.

The binding clip 3 comprises a support plate 31 and binding fingers 32, the support plate 31 is horizontally arranged at the top end of the guide pipe 2, and at least 3 binding fingers 32 are respectively arranged at the edge of the support plate 31 in a surrounding manner and hinged with the support plate 31.
