Description

Technical Field

[0001] The utility model relates to the technical field of surgical instruments, in particular to a burn plastic surgery scalpel. Background Art

[0002] The blades of traditional surgical scalpels used for burns, plastic surgery, etc. are disposable. When installing the scalpel blade, it is usually clamped with a tool and installed on the handle. The blade itself has a smooth surface and no specific clamping position. When clamping the blade, it is easy to slip and cause the blade to deform, affecting the accuracy of surgical cutting. Utility Model Content

[0003] In view of this, in order to solve the problems existing in the technical background, the utility model proposes a burn plastic surgery scalpel, and the specific technical solution is as follows:

[0004] A burn plastic surgery scalpel comprises a handle, a knife seat and a blade, wherein the knife seat is integrally connected to the knife seat, a blade is arranged on the knife seat, clamping positions are arranged at relative positions of the front and back sides of the blade, the clamping positions are recessed inwards to facilitate clamping by a clamping tool and are not easy to slip off, a long strip-shaped slot is provided in the middle of the blade, a matching embedding protrusion is provided on the knife seat, and the slot is embedded in the embedding protrusion.

[0005] Furthermore, a side wall of the knife handle at one end close to the knife seat is provided with abutment protrusions facing outwards, and the operator rests his thumb on the abutment protrusions when holding the knife, thereby increasing the holding stability of the user.

[0006] Furthermore, an extension handle is provided at one end of the knife handle, and a slide groove is provided on the knife handle and the extension handle. A slider is provided in the corresponding slide groove on the knife handle. When the extension handle is rotated 180 degrees to be in a straight line with the knife handle, the two slide grooves are connected. The slider is manually slid toward the position of the extension part so that the slider is fixed in the unfolded state of the extension handle when it is between the extension handle and the knife handle, thereby extending the overall length of the knife handle.

[0007] Furthermore, the thickness of the blade is 0.5-1 mm, and the clamping position is concave inward by 0.1 mm.

[0008] Furthermore, the surface of the clamping position is provided with strip-shaped anti-skid patterns to increase the anti-skid effect.

[0009] Furthermore, the clamping position is semi-elliptical.

[0010] Furthermore, the extension handle and the knife handle are rotatably connected by a hinge.

[0011] The above technical solution has the following beneficial effects:

[0012] The utility model clamps the clamping tool on the clamping position corresponding to the blade, and when the blade is installed on the blade seat through the clamping tool, the clamping position is concave inwardly and the surface of the clamping position is provided with anti-skid grooves, so the clamping tool is not easy to slip off and the blade surface is not easy to be deformed by clamping. The provided extension handle can extend the length of the handle to meet the requirements of different medical staff for the length of the handle. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1: See Figure 1-3The burn plastic surgery scalpel shown in the figure comprises a handle 1, a knife seat 3 and a blade 2, wherein the knife seat 3 is integrally connected to the knife seat 3, a blade 2 is arranged on the knife seat 3, a clamping position 22 is arranged at the relative position of the front and back sides of the blade 2, the clamping position 22 is recessed inwardly to facilitate clamping by a clamping tool and not easy to slip off, a long strip-shaped clamping groove 27 is opened in the middle of the blade 2, a matching embedding protrusion 31 is arranged on the knife seat 3, the clamping groove 27 is embedded in the embedding protrusion 31, and a supporting protrusion 11 is arranged outwardly on the side wall of one end of the knife handle 1 close to the knife seat 3, and the operator rests his thumb on the supporting protrusion 11 when holding the knife, thereby increasing the user's holding stability, see Figure 4 As shown, an extension handle 4 is provided at one end of the knife handle 1, and a slide groove 13 is provided on both the knife handle 1 and the extension handle 4. A slider 12 is provided in the corresponding slide groove 13 on the knife handle 1. When the extension handle 4 rotates 180 degrees and is in a straight line with the knife handle 1, the two slide grooves 13 are connected. The slider 12 is manually slid toward the position of the extension portion so that the slider 12 is fixed in the expanded state of the extension handle when it is between the extension handle 4 and the knife handle 1, thereby extending the overall length of the knife handle 1. The thickness of the blade 2 is 0.5-1mm, and the clamping position 22 is concave inward by 0.1mm. The surface of the clamping position 22 is provided with a strip-shaped anti-slip pattern to increase the anti-slip effect. The reinforcement is semi-elliptical, and the extension handle 4 and the knife handle 1 are rotatably connected by hinges.

[0025] When the utility model is used in practice, the blade 2 is embedded in the knife seat 3 by means of a clamping tool. After use, the operator holds the knife handle 1, with the thumb resting on the resting protrusion 11, and uses the clamping tool to remove or replace the blade 2. If the knife handle 1 needs to be extended for use, before use, the extended handle 4 is rotated 180 degrees to form a straight line with the knife handle 1, the two slide grooves 13 are connected, and the manual sliding block 12 is slid toward the position of the extended handle 4 so that the slider 12 is fixed in the extended handle 4 in the middle of the extended handle 4 and the knife handle 11, thereby extending the overall length of the knife handle 1.

[0026] See also Figure 6 As shown, the utility model clamps the clamping tool on the clamping position 22 corresponding to the blade 2. When the blade 2 is installed on the blade seat 3 through the clamping tool, the clamping position 22 is recessed inward and the surface of the clamping position 22 is provided with anti-slip grooves. The clamping tool is not easy to slip off and is not easy to cause the blade surface to be deformed by clamping. The provided extension handle 4 can extend the length of the handle 1 to meet the requirements of different medical staff for the length of the handle 1.
