Description

Technical Field

[0001] This utility model relates to the field of surgical instrument technology, and in particular to a convenient medical scalpel. Background Technology

[0002] Medical scalpels are one of the most commonly used surgical instruments in surgery. They are used to cut or dissect tissues. There are many types of medical scalpels, such as skin grafts and scalpels. Medical scalpels are suitable for various surgical procedures due to their advantages.

[0003] Most medical scalpels currently on the market are only used by combining the handle and the blade. After the surgery, the blade cannot be stored away, which may cause injury to medical staff, thereby increasing the safety hazards for medical staff during work, reducing the practicality of the device, and failing to meet the needs of users. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a convenient medical scalpel.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a convenient medical scalpel, comprising a handle, a blade disposed on the right rear end of the handle, a sheath disposed on the right side of the handle, a pressing plate disposed on the top of the sheath, a first limiting groove disposed at the center of the top end of the handle, and a plurality of second limiting grooves disposed on the right side of the top end of the handle, the pressing plate engaging with the first and second limiting grooves respectively, a rubber block fixedly connected to the bottom of the handle, a first groove disposed on the left side of the bottom of the sheath, and a second groove disposed on the bottom of the sheath, the rubber block being slidably connected to the interior of the second groove.

[0006] As a further description of the above technical solution:

[0007] An opening groove is provided on the right rear end of the knife handle, and a locking block is fixedly connected to the front side of the opening groove. A locking groove is provided on the front side of the blade, and the locking block engages with the locking groove.

[0008] As a further description of the above technical solution:

[0009] The front and rear sides of the knife handle are provided with sliding grooves in the lower middle part, and the front and rear sides of the inside of the knife sleeve are fixedly connected with sliders, which are slidably connected to the corresponding sliding grooves.

[0010] As a further description of the above technical solution:

[0011] Labels are provided on the front and rear sides of the knife handle.

[0012] As a further description of the above technical solution:

[0013] The blade sheath has anti-slip textures on both the upper and lower sides.

[0014] As a further description of the above technical solution:

[0015] The tool holder has a scale on the left side of its rear end.

[0016] As a further description of the above technical solution:

[0017] The outer edges of both the handle and the sheath are rounded.

[0018] This utility model has the following beneficial effects:

[0019] In this invention, pressing the pressing plate releases the fixed limit of the blade sheath. At this time, pushing the blade sheath to the right stores the blade, reducing the possibility of the blade accidentally injuring medical staff, thereby reducing safety hazards for medical staff during work, improving the practicality of the device, and meeting the needs of users.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1-6 This utility model provides an embodiment of a convenient medical scalpel, including a handle 1, a blade 2 disposed on the right rear end of the handle 1, and a sheath 3 disposed on the right side of the handle 1 for storing the blade 2. A pressing plate 4 is disposed on the top of the sheath 3; pressing the pressing plate 4 moves the sheath 3. A first limiting groove 5 is disposed in the middle of the top end of the handle 1, and multiple second limiting grooves 6 are disposed on the right side of the top end of the handle 1. The pressing plate 4 engages with the first limiting groove 5 and the second limiting grooves 6 respectively to limit and fix the sheath 3. A rubber block 7 is fixedly connected to the bottom of the handle 1 to further limit the movement of the blade sheath 3. A first groove 10 is provided on the bottom left side of the blade sheath 3, and a second groove 11 is provided on the bottom of the blade sheath 3. The rubber block 7 is slidably connected to the inside of the second groove 11, which plans the movement trajectory of the rubber block 7, making the rubber block 7 move more smoothly and can store the blade 2, reducing the possibility of the blade 2 causing accidental injury to medical staff, thereby reducing the safety hazards of medical staff during work, improving the practicality of the device, and meeting the needs of users.

[0030] The right rear end of the knife handle 1 has an opening groove 15 for holding the blade 2. A locking block 16 is fixedly connected to the front side of the opening groove 15. A locking groove 17 is provided on the front side of the blade 2. The locking block 16 engages with the locking groove 17 to limit and fix the blade 2, preventing it from shaking during operation and facilitating disassembly and replacement. The lower middle part of both the front and rear sides of the knife handle 1 has sliding grooves 9. Sliding blocks 8 are fixedly connected to the front and rear sides of the inside of the knife sleeve 3. The sliding blocks 8 are slidably connected to the corresponding sliding grooves 9. The movement path of the scalpel sheath 3 is marked to make its movement smoother. Labels 14 are set on the front and rear sides of the handle 1 to introduce the usage of the scalpel. Anti-slip textures 12 are set on the upper and lower sides of the sheath 3 to increase the friction between the medical staff's palm and the sheath 3. A scale 13 is set on the left rear end of the handle 1 to facilitate the measurement and recording of the length of the tissue to be cut. The outer edges of the handle 1 and the sheath 3 are rounded to protect the medical staff's palm and prevent hand injury.

[0031] Working principle: When the scalpel is needed for surgery, pressing the pressure plate 4 releases the limiting fixation of the scalpel sheath 3. Following the direction indicated on label 14, push the scalpel sheath 3 to the left to expose the blade 2 for surgical work. At this time, the pressure plate 4 engages with the first limiting groove 5, and the rubber block 7 is locked in the first groove 10, fixing the scalpel sheath 3 in place. During surgery, the scalpel sheath 3 will not fall off and affect the normal progress of the surgery. After the surgery, pressing both the pressure plate 4 and the rubber block 7 releases the limiting fixation of the scalpel sheath 3. Pushing the scalpel sheath 3 to the right causes the pressure plate 4 to move and engage with the second limiting groove 6. The rubber block 7 slides in the second groove 11, allowing the blade 2 to be stored, reducing the possibility of accidental injury to medical personnel and thus minimizing safety hazards during work. This improves the practicality of the device and meets the needs of users.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
