Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example one
Referring to fig. 1, the utility model discloses a surgical device for blunt tissue stripping and sharp tissue stripping, which comprises a first scissor handle 1 arranged linearly and a second scissor handle 2 arranged in a bending way. The front ends of the first scissor handle 1 and the second scissor handle 2 are respectively provided with a first shearing part 11 and a second shearing part 21, and the rear ends of the first scissor handle 1 and the second scissor handle 2 are respectively provided with a first handle part 12 and a second handle part 22. The first cutting part 11 and the first handle part 12 are integrally formed; the second cutout portion 21 is integrally formed with the second handle portion 22. The first scissor handle 1 is connected with the second scissor handle 2 in a cross-hinged mode. The opposite ends of the first shearing part 11 and the second shearing part 21 are respectively provided with a blade 5; a first finger ring 13 and a second finger ring 23 are integrally formed at one end of the first handle portion 12 facing away from the first cutting portion 11 and one end of the second handle portion 22 facing away from the second cutting portion 21, respectively. The first finger ring 13 and the second finger ring 23 are of the same size.
The peeling sheets 3 are welded to the ends of the first cutting portion 11 facing away from the first handle portion 12 and the second cutting portion 21 facing away from the second handle portion 22. The normal directions of the two peeling blades 3 are perpendicular to the longitudinal directions of the first cutting portion 11 and the second cutting portion 21, and also perpendicular to the axial direction in which the first scissor handle 1 and the second scissor handle 2 are hinged. When the two stripping pieces 3 are close to each other, the first shearing part 11 and the second shearing part 21 can shear to play a role of sharp stripping; when the two stripping sheets 3 are far away from each other, the two stripping sheets 3 can prop open the tissue to be stripped, so that the blunt stripping effect is achieved. So that the number of tool changes during the operation can be reduced.
Referring to fig. 3, when the first cut portion 11 and the second cut portion 21 are rotated to coincide, the opposing surfaces of the two release sheets 3 are brought into abutment, and the edges of the two release sheets 3 coincide. Therefore, the space range occupied by the two stripping pieces 3 when the two stripping pieces are abutted can be reduced, the stripping pieces 3 can move towards the tissue to be stripped conveniently, the stripping pieces 3 can extend into the gap of the tissue to be stripped more easily, and the mistaken touch of other tissues during operation can be avoided as much as possible.
Referring to fig. 1 and 2, an auxiliary support 4 for a finger to abut against is welded to one end of the first finger ring 13 facing away from the first cutting part 11. The auxiliary supporting member 4 is a sheet body, and the normal direction of the auxiliary supporting member 4 is parallel to the length direction of the first scissor handle 1. The surface of the auxiliary support 4 facing away from the first finger ring 13 is provided with a first non-slip pattern 41. The two opposite ends of the auxiliary supporting member 4 are bent towards the side away from the first finger ring 13, and the formed crease line is parallel to the rotation plane of the first scissor handle 1 and the second scissor handle 2.
In use, the thumb typically extends into the second finger loop 23 and the index finger extends into the first finger loop 13. Depending on the posture of the hand, the thumb extends obliquely into the second finger ring 23, while the index finger extends approximately vertically into the first finger ring 13. The thumb is abutted against the second finger ring 23, so that no gap exists between the thumb and the second finger ring 23, and the thumb can accurately control the rotation of the second scissor handle 2. However, there is a gap between the index finger and the first finger ring 13, and the index finger drives the first scissor handle 1 to rotate. However, after the index finger passes through the first finger ring 13, the middle finger can abut against the auxiliary support 4, and the index finger and the middle finger clamp the first finger ring 13 and the auxiliary support 4, so that the two fingers can accurately control the first scissor handle 1 to rotate. The first anti-slip pattern 41 increases the friction between the auxiliary support 44 and the index finger, so that the support of the index finger against the auxiliary support 44 is more stable.
Further, the auxiliary support member 4 that is the lamellar body can reduce the pressure that acts on the finger, and auxiliary support member 4 itself has certain thickness and has increased the interval between forefinger and the middle finger, and the joint department of buckling of finger can support by the department of buckling of auxiliary support member 4 moreover for the finger can be more comfortable the laminating on auxiliary support member 4, accords with ergonomic design more.
Example two
Referring to fig. 4, the present embodiment is different from the first embodiment in that the auxiliary supporting member 4 is a "U" shaped block, a space for fingers to be placed is left in a U-shaped opening of the auxiliary supporting member 4, and the U-shaped opening faces a side away from the first finger ring 13. The inner surface of the U-shaped opening of the auxiliary supporting member 4 is provided with a second anti-slip thread 42.
When forefinger and middle finger centre gripping first ring 13 and auxiliary support piece 4, stretch into the intraoral forefinger of U type and can also assist and drive first scissors handle 1 and remove, make the hand more stable to the rotatory control of first scissors handle 1, and then can reduce forefinger and middle finger to first ring 13 and auxiliary support piece 4's centre gripping dynamics. Second anti-slip threads 42 increase the friction between auxiliary support 4 and the index finger, making the control of first scissor handle 1 more stable when the index finger abuts auxiliary support 4.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
