Abstract

The utility model belongs to a surgical cutting instrument.

The utility model discloses it is by two shear blades and with the shear blade respectively even handle as an organic whole constitute, two shear blades are articulated by the round pin axle, two shear blade middle parts downwarping. The utility model discloses simple structure, operation are accurate, safety, can once accomplish the excision of small size pathological change tissue, have shortened the operation time, master easily. Is suitable for cutting the scattered residual granulation wound surfaces and is particularly beneficial to children.

Description

Tissue scissors

This utility model belongs to a kind of surgery cutting device.

Clinically at present, strike off and adopt scalpel the operation tool of small size pathological tissues (as granulation tissue), because in operation, knife face is difficult to coincide with the tissue of scraping, and the tissue that at every turn strikes off is few.In order to strike off the bottom pathological tissues, need repeatedly shaving tissue, the used time of result is long, and bleeding increases.With common tissue scissors, can reach certain effect, but because the shear blade of tissue scissors, damages little wound surface normal structure on every side easily for upwarping structure gradually, and do not reach the degree of depth and the area of wiping out.

The purpose of this utility model is to address the above problem, and a kind of accurately removal lesion tissue is provided, easy to operate, save time, safety tissue scissors.

This utility model is formed by two shear blades with the handle that shear blade is connected as a single entity respectively, and two shear blades are hinged by bearing pin, and two shear blades middle part is bent downwardly.

This utility model is simple in structure, operation is accurate, safety, can once finish the excision of small size pathological tissues, has shortened operating time, grasps easily.Be suitable for the excision of the remaining granulation wound of being dispersed in property of pilosity, to child's advantageous particularly.

Below in conjunction with accompanying drawing this utility model is described in detail.

As shown in Figure 1, 2, this utility model is formed by two shear blades 1 with the handle 3 that shear blade is connected as a single entity respectively, and two shear blades are hinged by bearing pin 2, and two shear blades middle part 4 is bent downwardly.Can once finish the excision of small size pathological tissues so exactly.Because diameter is 4～5cm the small size pathological tissues (as granulation tissue), two shear blade bottom surfaces are bent downwardly the degree of depth and are advisable with 1～2cm.

As shown in Figure 3, be provided with a bending section 5 on two shear blade tops, the flexibility of this bending section is greater than the bending section at middle part.Increased the scope of application of the present utility model.

Claims (3)

1. Tissue scissors, which are composed of two scissors blades and handles respectively connected with the scissors blades. The two scissors blades are hinged by pin shafts. The feature is that the middle parts of the two scissors blades are bent downward. 2. The tissue scissors according to claim 1, characterized in that the downward bending depth of the middle parts of the two scissor blades is preferably 1-2 cm. 3. The tissue scissors according to any one of claims 1-2, characterized in that there is a curved section at the top of the two scissor blades, and the curvature of this curved section is greater than that of the middle curved section.
