[0025] The purpose, advantages and features of the present invention will be illustrated and explained through the non-limiting description of the following preferred embodiments. These embodiments are only typical examples of the application of the technical solution of the present invention, and any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection claimed by the present invention.

[0026] The utility model discloses an electrolytic polishing quick-change device for a surgical knife, comprising: Figure 1 The carrier plate 1 shown in the figure has a tray 2 arranged on the carrier plate 1. Figure 1 As shown, the carrier 1 is provided with a clamping block 11, which is located at the corner of the tray 2 and is used to clamp and limit the position of the tray 2, effectively preventing the tray 2 from being displaced from the carrier 1. Tray handles 21 are provided at both ends of the tray 2, and the tray 2 can be installed on the carrier 1 or taken from the carrier 1 by applying a downward or upward force to the tray handles 21.

[0027] The tray 2 is evenly distributed with knife holder assemblies 3 for placing surgical blades. The tray 2 is provided with through holes 20 for connecting the knife holder assemblies 3. Specifically, as Figures 2 to 5 As shown, the knife holder assembly 3 includes a knife holder 1 31 connected to the tray 2, and a knife holder 2 32 detachably arranged on the side wall of the knife holder 1 31. The knife holder 1 31 is in a U shape, wherein two side walls of the U shape are formed with connecting holes 230, and the connecting holes 230 correspond to the through holes 20 and are connected via a connecting shaft. The groove bottom part of the knife holder 1 31 is evenly distributed with a group of sockets 30 for installing a scalpel.

[0028] Specifically, the tool holder 2 32 is arranged on the outer side of the groove bottom of the tool holder 1 31, and the two ends of the tool holder 2 32 are connected to the tool holder 1 31 through guide bolts 312, and the guide bolts 312 move from the tool holder 2 32 to the direction of the tool holder 1 31; that is, the tool holder 2 32 is provided with bolt holes corresponding to the tool holder 1 31 one by one, so that the guide bolts 312 can pass through.

[0029] Furthermore, the main body of the tool holder 2 32 is also formed with a plunger hole for installing a plunger 321, and the plunger 321 moves along the setting direction of the plunger hole; and the end of the plunger 321 protrudes from the side wall of the tool holder 2 32 and is inserted into the tool holder 1 31. The guide bolt 312 is located between two adjacent plunger holes 320.

[0030] like Figure 3 to Figure 4 As shown, a self-locking pin 322 is further provided between the tool holder 1 31 and the tool holder 2 32. The self-locking pin 322 is located in the groove bottom of the tool holder 1 31, and its end passes through the tool holder 2 32 and is assembled with a self-locking nut to drive the tool holder 1 31 or the tool holder 2 32 to move and adjust the gap between the two. Figure 6 As shown, the self-locking pin 322 includes an integrally arranged shaft portion 3221 and an end portion 3222. The diameter of the end portion 3222 is larger than the diameter of the shaft portion 3221, and a protrusion 3223 is provided on the end surface of the end portion 3222 close to the shaft portion 3221, and the protrusion 3223 corresponds to the protrusion hole on the tool holder 1 31. The diameter of the end of the shaft portion 3221 is smaller than the diameter of the portion close to the end portion 3222, and the self-locking nut is assembled with the shaft portion 3221. The self-locking pin 322 is used to guide the positions of the tool holder 1 31 and the tool holder 2 32, and at the same time, the gap between the tool holder 1 31 and the tool holder 2 32 is effectively prevented from becoming larger, thereby ensuring the stability of the placement position of the surgical blade and the safety of use during the electrolytic polishing process.

[0031] In order to prevent the first tool holder 31 and the second tool holder 32 from having a hard contact during the movement, the present application preferably further provides an elastic connector 323 between the first tool holder 31 and the second tool holder 32. The elastic connector 323 includes but is not limited to a compression spring, and can also be other components with elastic functions disclosed in the prior art, which will not be described in detail here. The elastic connector 323 can effectively prevent the first tool holder and the second tool holder from colliding, thereby extending the service life of both.

[0032] like Figure 5As shown, a group of sockets 30 for mounting a scalpel are formed on the tool holder 31; each socket 30 corresponds to an avoidance hole 310 and a plunger hole 320. The avoidance hole 310 is used to accommodate the probe on the electrolysis device, and the avoidance hole 310 is arranged at the bottom of the tool holder 31, which is coaxially arranged and connected with the socket 30. Since the probe structure is a known prior art, it is not described here. The length of the handle of the scalpel entering the socket 30 and the avoidance hole 310 is preferably 6.5±0.5mm, and contacts with the probe inserted in the avoidance hole 310, so that the conductive probe contacts the scalpel and generates current on the scalpel, thereby realizing the electrolytic polishing operation of the scalpel. When the handle of the scalpel enters the avoidance hole 310, it is abutted by the plunger in the plunger hole 320, and the scalpel is clamped in the socket 30. The plunger hole 320 is located on the side wall of the first blade holder 31 so that the plunger 321 on the second blade holder 32 can pass through and abut against the surgical knife.

[0033] The following is a brief description of the working process of this application:

[0034] S1, placing a scalpel in each socket 30 on the knife holder assembly 3, with the blade of the scalpel away from the socket 30;

[0035] S2, connecting the second knife holder 32 to the first knife holder 31 through the guide bolt 312, and making the end of the plunger 321 abut against the end of the scalpel inserted into the socket 30; limiting the position of the scalpel in the width direction to ensure the stability of the placement position of the scalpel;

[0036] S3, insert the self-locking pin 322 from the second tool holder 32, and penetrate the second tool holder 32 and the first tool holder 31, and at the same time, rotate the self-locking pin 322 to self-lock, so as to ensure that it is stably connected to the tool holder assembly 3. The self-locking pin 322 limits the position of the middle section of the tool holder 1 31 and the second tool holder 32, so as to further enhance the connection stability of the tool holder assembly 3;

[0037] S4, inserting the probe into the avoidance hole 310 and contacting the part of the scalpel plugged into the socket 30, so as to energize the scalpel to achieve electrolytic polishing operation;

[0038] S5, taking out one or more tool holder assemblies 3 from the tray 2, placing a group of scalpels on the same tool holder assembly 3 to the electrolytic polishing position for batch polishing operation, thereby improving work efficiency and achieving high-precision flattening polishing.

[0039] There are many implementation methods of the utility model, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the utility model.
