Description

Technical Field

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

[0002] Surgery is one of the most direct and effective methods for treating diseases, helping patients quickly remove diseased tissue and restore their health. During surgery, the scalpel plays a crucial role as a doctor's indispensable assistant. Currently, the most commonly used stainless steel scalpels both domestically and internationally consist of a blade and a handle. To ensure blade cleanliness, modern blades are generally disposable.

[0003] In existing technology, the blade is mounted on the handle. The process of attaching and detaching the blade requires aligning it at the correct angle and applying force to engage or disengage the blade from the handle. This process is cumbersome, time-consuming, and labor-intensive. Furthermore, if medical personnel apply incorrect angles or excessive force during this process, they are prone to being cut by the blade. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a medical surgical instrument to solve the above problems.

[0005] The present invention adopts the following technical solution:

[0006] The medical surgical instrument includes a blade holder and a blade. One side of the blade holder is configured as a cross-section, and the other side has a sliding groove. A limiting seat is provided in the cross-section, and a pusher blade is slidably mounted in the sliding groove. The pusher blade has a pusher post, and the limiting seat and the pusher post are positioned front and rear. The blade has a limiting groove and a mounting groove that are connected front and rear, and the width of the limiting groove is narrower than that of the mounting groove. The blade is located in the cross-section, and the limiting seat and the pusher post are both located in the mounting groove. A clamping groove is provided at the end of the cross-section in the blade holder, and the clamping groove is positioned towards the tail of the blade.

[0007] Furthermore, the front end of the limiting seat has a pair of cuts forming a locking head, the width of which matches the width of the limiting groove.

[0008] Furthermore, a shallow groove is formed on the side of the tool holder, and a sliding groove is formed at the front end of the shallow groove, with the pusher blade located within the shallow groove.

[0009] Furthermore, the shallow groove has a slot at its tail, the front end of the pusher blade has an anti-slip texture, and the rear end has a matching block corresponding to the slot.

[0010] The beneficial effects of this utility model are as follows: Medical staff use pliers to clamp the blade, and then place the blade into the installation area as required. The limiting seat and the push post are both located in the installation groove. Finally, the medical staff pushes the blade backward a short distance. During this process, the blade retracts a short distance under the push of the push post until the tail of the blade is completely pushed into the clamping groove. At the same time, the front end of the limiting seat is engaged in the limiting groove, and the blade installation is completed. It can be seen that the whole installation process is relatively simple and convenient. Attached Figure Description

[0014] To make the purpose, technical solution, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0016] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0017] Combination Figure 1-3 As shown, the medical surgical instrument includes a blade holder 1 and a blade 2. One side of the blade holder is configured as a cross-section 3, and the other side has a sliding groove 4. A limiting seat 5 is provided in the cross-section 3. A pusher blade 6 is slidably disposed in the sliding groove 4. A pusher post 7 is provided on the pusher blade 6, and the limiting seat 5 and the pusher post 7 are arranged front and rear. The blade 2 has a limiting groove 8 and a mounting groove 9 that are connected front and rear, and the width of the limiting groove is narrower than that of the mounting groove. The blade 2 is located in the cross-section 3, and the limiting seat 5 and the pusher post 7 are both located in the mounting groove 9. A clamping groove 10 is provided at the end of the cross-section 3 in the blade holder 1, and the clamping groove 10 is arranged facing the tail of the blade 2.

[0018] During surgery, the scalpel plays a crucial role as a doctor's indispensable assistant. Currently, the stainless steel scalpels commonly used both domestically and internationally consist of a blade and a handle. To ensure the cleanliness of the blade, in this embodiment, the blade is a disposable blade, which is mounted on the blade holder.

[0019] In this structure, a shallow groove 11 is formed on the side of the blade holder 1, and a sliding groove 4 is formed at the front end of the shallow groove 11. The pusher blade 6 is located in the shallow groove 11. The blade holder serves as a mounting carrier, with one side having a cross-section and the other side having the shallow groove. A portion of the pusher blade is located within the shallow groove. On the one hand, when the pusher blade moves back and forth, the shallow groove can guide and limit its movement, making the pusher blade move more stably. On the other hand, the shallow groove accommodates the pusher blade, making the entire surgical instrument look more aesthetically pleasing.

[0020] The cross-section serves as the installation area for the blade. When installing the blade within this area, the blade holder can be placed parallel with the cross-section facing upwards, and the pusher blade is in its initial position. Medical personnel take a blade to be installed and clamp it with pliers or other tools. Then, they place the blade into the installation area as required, with both the limiting seat and the pusher pin located within the installation groove. Finally, the medical personnel push the pusher blade backward a short distance. During this process, the blade retracts a short distance under the pusher pin's influence until the tail of the blade is completely pushed into the clamping groove. Simultaneously, the front end of the limiting seat engages with the limiting groove, completing the blade installation. Therefore, the entire installation process is relatively simple and safe.

[0021] As a specific structure, such as Figure 1 The shallow groove 11 has a slot 12 at its tail end, and the front end of the push blade 6 has an anti-slip texture 13, while the rear end has a matching locking block 13 corresponding to the slot 12. During the process of pushing the push blade backward, the medical staff presses the anti-slip texture with their fingers and then pushes the push blade backward, moving it a short distance until the locking block engages with the slot, thus completing the blade installation.

[0022] During the installation process described above, once the blade is installed, the locking block is positioned within the slot, which serves as a positioning mechanism. The locking block locks the push post, preventing the blade from wobbling back and forth during use and improving the stability of the scalpel. Furthermore, the limiting seat and clamping groove limit the forward and backward position of the blade, further enhancing the stability of the scalpel during use.

[0023] To remove the blade from the tool holder, simply use pliers or other tools to grip the tip of the blade. Apply slight force with the pliers and push the blade forward. The blade will move the push pin forward a short distance until it returns to its initial position. Both the limit seat and the push pin will then be within the mounting groove, and the tail of the blade will disengage from the groove. At this point, the blade can be removed from the tool holder. As can be seen, disassembling the entire blade is equally simple and safe.

[0024] Figure 1In this design, the front end of the slot 12 has a ramp 14, and the entire pusher blade is made of plastic. As the pusher blade moves forward and returns to its initial position, the block will slightly deform and disengage from the slot via the ramp.

[0025] Furthermore, as a preferred structure, Figure 3 In the diagram, the front end of the limiting seat 5 has a pair of notches forming a locking head 51, the width of which matches the width of the limiting groove 5. In the illustration, the width of the limiting seat matches the width of the mounting groove, and the width of the locking head matches the width of the limiting groove. When the blade is placed within the blade installation area as required, both the limiting seat and the push post are located within the mounting groove. Then, the pusher is moved backward, and the blade retracts backward under the action of the push post until the locking head engages with the limiting groove, and the tail of the blade is completely pushed into the clamping groove. At this point, the blade installation is complete.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
