[0012] Furthermore, the support components are made of ceramic material.
[0013] Furthermore, the edge of the bracket is provided with multiple notches, and the inner side of the cover is provided with multiple protrusions, with each protrusion corresponding to a notch and extending into the notch.
[0014] Furthermore, the electrode sheet is bonded to the support surface using epoxy adhesive.
[0015] According to another aspect of the present invention, a surgical forceps is provided, the surgical forceps including a medical jaw, the medical jaw being the aforementioned medical jaw.

[0041] Combination Figures 1 to 5 As shown, according to a specific embodiment of this application, a medical clamp is provided.
[0042] Specifically, the medical jaw 10 includes a jaw body and an electrode plate 2. The jaw body has a support surface, and the support surface is provided with an insulating protrusion 1. The electrode plate 2 is connected to the support surface, the insulating protrusion 1 passes through the electrode plate 2, and part of the insulating protrusion 1 protrudes from the outer surface of the electrode plate 2.
[0043] In the embodiments of this application, an insulating protrusion 1 is provided on the support surface of the jaw body. The electrode plate 2 is connected to the support surface of the jaw body. The insulating protrusion 1 passes through the electrode plate 2 and protrudes outward from the outer surface of the electrode plate 2, thereby preventing the two electrode plates 2 on the surgical forceps from touching. In the above solution, it is not necessary to provide an insulating protrusion 1 on the electrode plate 2. It is only necessary to open a through hole 24 suitable for the insulating protrusion 1 to pass through on the electrode plate 2, which simplifies the manufacturing process of the electrode plate 2 and reduces the manufacturing cost.
[0044] Furthermore, the insulating protrusion 1 is integrally formed on the support surface, which can effectively prevent the insulating protrusion 1 from falling off.
[0045] Furthermore, the jaw body includes: a bracket 3, a support member 4, and a covering member 5. The support member 4 is connected to the bracket 3, with the support surface located on the side of the support member 4 away from the bracket 3. The covering member 5 is connected to the edge of the bracket 3, the edge of the support member 4, and the edge of the electrode sheet 2. The jaw body has a spliced structure, reducing the manufacturing difficulty of the jaw body. In addition, each splice member can be made of a corresponding material according to its application to improve the service life of the jaw body.
[0046] In the embodiments of this application, such as Figure 1As shown, one end of the bracket 3 is provided with a hinge seat 33, and the two medical jaws 10 are hinged together by the hinge seat 33. Specifically, the hinge seat 33 is provided with a pin hole 34 and a waist-shaped hole 32. The hinge seat 33 on one of the medical jaws 10 is fixedly connected to the fixing pin 7 through the pin hole 34, and the hinge seat 33 on the other medical jaw 10 is rotatably connected to the fixing pin 7 through the pin hole 34, so as to realize the hinge of the two medical jaws 10. The waist-shaped holes 32 on the two medical jaws 10 are arranged opposite each other, and the sliding pin 8 passes through the waist-shaped hole 32. External force drives the sliding pin 8 to slide along the length direction of the waist-shaped hole 32 to realize the opening and closing action of the jaws.
[0047] like Figure 1 As shown, the support member 4 is connected to the bracket 3. An insulating protrusion 1 is provided on the side of the support member 4 away from the bracket 3. The insulating protrusion 1 is integrally formed with the support member 4. The support member 4 is injection molded. The insulating protrusion 1 on the support member 4 can be adjusted to the corresponding height according to the usage requirements to control the gap between the two electrode plates 2.
[0048] like Figure 1 , Figure 4 As shown, electrode sheet 2, support member 4, and bracket 3 are sequentially bonded together to form an assembly. Covering member 5 encloses the outside of this assembly to make the connection between the three more secure. Specifically, after electrode sheet 2, support member 4, and bracket 3 are sequentially bonded together, they are placed in the corresponding mold for secondary injection molding, that is, covering member 5 is an injection molded part.
[0049] like Figure 1 , Figure 2 As shown, the electrode sheet 2 is provided with a through hole 24. The depth of the through hole 24 is less than the height of the insulating protrusion 1. The insulating protrusion 1 on the support member 4 passes through the through hole 24, and part of the insulating protrusion 1 extends outward after passing through the through hole 24.
[0050] Preferably, the electrode sheet 2 is bonded to the support surface with epoxy adhesive, and the support member 4 is bonded to the bracket 3 with epoxy adhesive.
[0051] Preferably, the support 4 is made of ceramic material. Ceramic material not only has the characteristics of high temperature and high pressure resistance, but also has good thermal conductivity, which can conduct heat away from the electrode plate 2 in a timely manner, avoiding heat accumulation and thermal damage to blood vessel tissue.
[0052] Preferably, the bracket 3 is manufactured using powder metallurgy, which can improve the rigidity of the bracket 3 and strengthen the clamping force of the jaws.
[0053] Furthermore, the end of the support member 4 is provided with a slot 41, which extends through the thickness direction of the support member 4; the end of the electrode sheet 2 is provided with a locking block 21, which extends along the thickness direction of the electrode sheet 2, and at least a portion of the locking block 21 is inserted into the slot 41. The end of the electrode sheet 2 is connected to the support member 4 through a locking structure to prevent the end of the electrode sheet 2 from warping due to deformation, and also to make the connection between the electrode sheet 2 and the support member 4 more secure, preventing the electrode sheet 2 from falling off.
[0054] Specifically, such as Figure 2 , Figure 3 As shown, the tail end of the support member 4 is provided with two slots 41, which are spaced apart along the width direction of the support member 4, and the slots 41 are connected through the support member 4 along the thickness direction. The tail end of the electrode sheet 2 is provided with two locking blocks 21, which are spaced apart along the width direction of the electrode sheet 2, and the locking blocks 21 extend along the thickness direction of the electrode sheet 2. The locking blocks 21 move along the thickness direction of the support member 4 so that the locking blocks 21 are inserted into the slots 41.
[0055] In the embodiments of this application, such as Figure 2 , Figure 4 As shown, the support member 4 has a step 42 at its edge, which extends along the length of the support member 4. The electrode plate 2 has a flange 23, which extends along the length of the electrode plate 2 and abuts against the surface of the step 42. The flange 23 abuts against the surface of the step 42, meaning it covers the outer surface of the step 42, increasing the contact area between the support member 4 and the electrode plate 2, thus making the connection between the support member 4 and the electrode plate 2 more secure.
[0056] Furthermore, the electrode sheet 2 is provided with a wire groove 22, which extends along the length of the electrode sheet 2 and is connected to the locking block 21. Here, the locking block 21 serves as a connector, simplifying the structure of the electrode sheet 2.
[0057] Specifically, such as Figure 1 , Figure 3 As shown, the wire groove 22 has a U-shaped structure. The wire groove 22 is connected to the end of the card block 21 that is away from the electrode plate 2, so that the electrode wire 6 is set away from the electrode plate 2 to avoid the electrode plate 2 from overheating and affecting the electrode wire 6.
[0058] Furthermore, the edge of the bracket 3 is provided with multiple notches 31, and the inner side of the covering 5 is provided with multiple protrusions 51. The protrusions 51 are arranged in a one-to-one correspondence with the notches 31, and the protrusions 51 extend into the notches 31. The cooperation between the protrusions 51 and the notches 31 can increase the contact area between the bracket 3 and the covering 5, thereby making the connection between the two more secure.
[0059] Specifically, such as Figure 1As shown, the edge of the bracket 3 is provided with multiple notches 31, which are spaced apart along the length of the bracket 3. The covering part 5 is an injection molded part. The bracket 3 is placed into the corresponding mold, and slurry is injected into the mold. The slurry wraps the outer edge of the bracket 3 to form the covering part 5. Some of the slurry flows into the notches 31 to form protrusions 51 on the covering part 5.
[0060] According to another specific embodiment of the present invention, a surgical forceps is provided, the surgical forceps including a medical jaw 10, the medical jaw 10 being the medical jaw 10 in the above embodiment.
[0061] Specifically, such as Figure 5 As shown, the surgical forceps includes two medical jaws 10, which are hinged together by a hinge base 33. A sliding pin 8 passes through a waist-shaped hole 32 on the hinge base 33. The driving part of the surgical forceps is connected to the sliding pin 8. The driving part drives the sliding pin 8 to move repeatedly along the length direction of the waist-shaped hole 32 to realize the opening and closing of the surgical forceps.
[0062] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:
[0063] 1. An insulating protrusion 1 is provided on the support surface of the jaw body. The electrode plate 2 is connected to the support surface of the jaw body. The insulating protrusion 1 passes through the electrode plate 2 and protrudes outward from the outer surface of the electrode plate 2. The insulating protrusion 1 prevents the two electrode plates 2 on the surgical forceps from touching. The electrode plate 2 does not need to be provided with the insulating protrusion 1. Only a through hole 24 suitable for the insulating protrusion 1 to pass through is required on the electrode plate 2, which simplifies the manufacturing process of the electrode plate 2 and reduces the manufacturing cost.
[0064] 2. The insulating protrusion 1 is integrally formed on the support surface, which can effectively prevent the insulating protrusion 1 from falling off.
[0065] 3. The end of the electrode sheet 2 is connected to the support member 4 through a snap-fit structure to prevent the end of the electrode sheet 2 from warping due to deformation. At the same time, it also makes the connection between the electrode sheet 2 and the support member 4 more secure and prevents the electrode sheet 2 from falling off.
[0066] 4. The support component 4 is made of ceramic material. Ceramic material not only has the characteristics of high temperature and high pressure resistance, but also has good thermal conductivity, which can conduct heat away from the electrode plate 2 in a timely manner, avoiding heat accumulation and thermal damage to blood vessel tissue.
