Technical Field

[0001] This application relates to the field of medical device packaging technology, and in particular to a surgical tool fixing device. Background Technology

[0002] An ultrasonic scalpel is a surgical instrument that uses ultrasonic energy to cut tissue. The scalpel's head and shaft are precision components, easily damaged by external impacts. Therefore, during transportation and storage, the ultrasonic scalpel needs to be secured in its packaging box using clamps. These clamps lock the scalpel in place, preventing movement or shaking during transport and ensuring it remains in good condition to avoid affecting its performance during surgery.

[0003] However, in related technologies, the clamping effect on fixing the ultrasonic scalpel shank is not good, and the shank still has the risk of loosening. During transportation and storage, the shank is easily damaged. Utility Model Content

[0004] Therefore, it is necessary to provide a surgical tool fixation device to address the issue of improving the fixation effect of ultrasonic scalpels.

[0005] A surgical tool fixing device is disclosed. The surgical tool includes a scalpel handle. The fixing device includes a housing. The housing has a scalpel handle groove for accommodating the scalpel handle. The scalpel handle groove has a fixing position for fixing the scalpel handle. The fixing position includes a limiting part and a squeezing part disposed opposite to each other. The limiting part and the squeezing part are respectively disposed on opposite side walls of the scalpel handle groove. The squeezing part abuts against the scalpel handle and pushes the scalpel handle towards the limiting part, so that the scalpel handle is locked between the squeezing part and the limiting part.

[0006] The technical solution will be further explained below:

[0007] In one embodiment, the limiting portion includes a limiting protrusion that protrudes from one side of the tool bar groove along its length and is disposed near the opening of the tool bar groove. The projection of the limiting protrusion in the depth direction of the tool bar groove can cover at least a portion of the tool bar; and / or,

[0008] The limiting part includes a limiting groove, which is formed on one side of the groove wall of the tool bar groove along the length direction and extends along the length direction of the tool bar groove. The limiting groove can accommodate at least a portion of the tool bar.

[0009] In one embodiment, the pressing portion includes an abutting protrusion disposed on the groove wall of the tool bar groove, and the abutting protrusion protrudes from the groove wall of the tool bar groove in a direction close to the limiting portion.

[0010] In one embodiment, each of the extrusion portions includes at least two abutting protrusions, which are spaced apart along the length of the cutter bar groove. An arcuate groove is provided between two adjacent abutting protrusions, and the arcuate groove is recessed into the groove wall of the cutter bar groove in a direction away from the limiting portion.

[0011] In one embodiment, the number of fixing positions is at least two, and the at least two fixing positions are spaced apart along the length direction of the tool slot.

[0012] In one embodiment, along the length of the cutter bar groove, the limiting portion and the extrusion portion are alternately arranged on each side wall of the cutter bar groove.

[0013] In one embodiment, the housing includes:

[0014] The body portion has a first surface, and the tool slot is formed on the first surface;

[0015] A flange portion is provided along the edge of the first surface and is provided at an angle to the first surface. A reinforcing rib is connected between the flange portion and the first surface.

[0016] In one embodiment, the number of reinforcing ribs is at least two, and the at least two reinforcing ribs are spaced apart along the edge of the first surface.

[0017] In one embodiment, the housing is further provided with a take-out slot, the blade groove extends through all the take-out slots, the width of the take-out slot is greater than the width of the blade groove, and the depth of the take-out slot is greater than the depth of the blade groove.

[0018] In one embodiment, the surgical tool further includes a handle, and the housing is provided with a handle slot for accommodating the handle, the handle slot being connected to one end of the blade slot.

[0019] The aforementioned surgical tool fixing device features a limiting part on one side wall of the blade groove in the housing, which confines the blade within the groove. Simultaneously, a pressing part on the other side wall of the blade groove, opposite the limiting part, abuts against the blade and pushes it towards the limiting part, maintaining the blade locked within the limiting part.

[0037] One embodiment of this application provides a surgical tool fixing device for securing surgical tools during packaging. The surgical tools include, but are not limited to, ultrasonic scalpels; any surgical tool with an elongated shaft is within the scope of this solution. Therefore, a surgical tool may include a blade with an elongated shaft and a handle connected to the blade and driving the blade. Specifically, see... Figure 1 as well as Figure 2 One embodiment of the surgical tool fixing device includes a housing with a blade groove 11 for accommodating a blade 41 of the surgical tool. The blade groove 11 also includes a fixing position 12 for fixing the blade 41. (In conjunction with...) Figure 3 as well as Figure 4 The fixed position 12 includes a limiting part 121 and a pressing part 122 arranged opposite to each other. The limiting part 121 and the pressing part 122 are respectively provided on opposite side groove walls of the tool bar groove 11. The limiting part 121 is used to limit and cooperate with the tool bar 41, and the pressing part 122 is used to abut against the tool bar 41 and push the tool bar 41 towards the limiting part 121, so that the tool bar 41 is locked between the pressing part 122 and the limiting part 121.

[0038] The aforementioned surgical tool fixing device features a limiting part 121 on one side wall of the blade groove 11 in the housing, which confines the blade 41 within the groove. Simultaneously, a pressing part 122, opposite the limiting part 121, is provided on the other side wall of the blade groove 11. This pressing part 122 abuts against the blade 41 and pushes it towards the limiting part 121, maintaining the locking state between the limiting part 121 and the blade 41. This improves the fixing effect on the blade 41, preventing separation of the blade 41 from the limiting part 121 during transportation and storage due to bumps or other reasons. This also avoids the problem of the blade 41 becoming detached from the blade groove 11 and susceptible to physical damage.

[0039] See Figure 5 as well as Figure 6 Optionally, in one embodiment, the limiting part 121 includes a limiting protrusion 1211, which is disposed on one side of the groove wall of the tool bar groove 11 along the length direction and close to the groove opening of the tool bar groove 11. The projection of the limiting protrusion 1211 in the depth direction of the tool bar groove 11 can cover at least a portion of the tool bar 41. Thus, after the tool bar 41 is placed into the tool bar groove 11, the limiting protrusion 1211 can be engaged with the top of the tool bar 41, thereby preventing the tool bar 41 from coming out of the tool bar groove 11. At the same time, in conjunction with the squeezing effect of the squeezing part 122 on the tool bar 41, the tool bar 41 can be firmly locked below the limiting protrusion 1211, preventing the tool bar 41 from loosening.

[0040] See also Figure 6 Optionally, in one embodiment, the limiting part 121 may further include a limiting groove 1212. The limiting groove 1212 is provided on one side of the groove wall of the tool bar groove 11 along the length direction, and the limiting groove 1212 extends along the length direction of the tool bar groove 11. The limiting groove 1212 can accommodate at least a portion of the tool bar 41. Thus, after the tool bar 41 is placed into the tool bar groove 11, the squeezing effect of the squeezing part 122 can push the tool bar 41 into and limit it in the limiting groove 1212. The groove wall of the limiting groove 1212 engages with the tool bar 41, thereby also preventing the tool bar 41 from coming out of the tool bar groove 11.

[0041] See Figure 4Optionally, in one embodiment, the pressing part 122 includes an abutment protrusion 1221, which is disposed on one side of the groove wall of the tool bar groove 11 along its length direction, and protrudes from the groove wall of the tool bar groove 11 toward the limiting part 121. Thus, after the tool bar 41 is placed into the tool bar groove 11, the abutment protrusion 1221 abuts against the side of the tool bar 41 away from the limiting part 121, thereby pressing the tool bar 41 toward the side where the limiting part 121 is located, maintaining the tool bar 41 in a locked state with the limiting part 121, and preventing the tool bar 41 from loosening from the limiting part 121. Exemplarily, the surface of the abutment protrusion 1221 that abuts against the tool bar 41 is an arc surface, thereby preventing the abutment protrusion 1221 from scratching the tool bar 41.

[0042] Furthermore, each extrusion part 122 includes at least two abutting protrusions 1221, which are spaced apart along the length of the cutter bar groove 11. An arc-shaped groove 1222 is provided between adjacent abutting protrusions 1221, and the arc-shaped groove 1222 is recessed into the groove wall of the cutter bar groove 11 in a direction away from the limiting part 121. Exemplarily, in this embodiment, each extrusion part 122 includes two abutting protrusions 1221, both of which are used to abut against the cutter bar 41, and an arc-shaped groove 1222 is provided between the two abutting protrusions 1221. Thus, after the cutter bar 41 is placed into the cutter bar groove 11, the extrusion part 122 abuts against the cutter bar 41, and under the action of a reaction force, the groove wall on the side where the extrusion part 122 is located undergoes a certain amount of elastic deformation. Since the groove wall of the arc groove 1222 is arched, when the groove wall of the tool bar groove 11 undergoes elastic deformation, the groove wall of the arc groove 1222 can resist the elastic deformation, thereby enhancing the rigidity of the groove wall of the tool bar groove 11, thus strengthening the squeezing force of the abutment protrusion 1221 on the tool bar 41, and further enhancing the fixing effect on the tool bar 41.

[0043] See Figure 3 In one embodiment, the number of fixing positions 12 is at least two, and the at least two fixing positions 12 are spaced apart along the length direction of the tool holder groove 11. For example, see... Figure 3 In this embodiment, four fixing positions 12 are provided. These four fixing positions 12 are spaced apart along the length of the tool holder groove 11 and are used to fix different positions of the tool holder 41. Understandably, the number of fixing positions 12 is not limited to four. In other embodiments, the number of fixing positions 12 can be set according to the length of the tool holder 41. For example, the number of fixing positions 12 can also be one, two, three, five, or more. By using multiple fixing positions 12 to jointly fix the tool holder 41, the fixing effect on the tool holder 41 can be further improved.

[0044] See Figure 3In one embodiment, along the length of the tool holder groove 11, the limiting portion 121 and the pressing portion 122 on each side wall of the tool holder groove 11 are alternately arranged. For example, the arrangement sequence of the limiting portion 121 and the pressing portion 122 on one side wall of the tool holder groove 11 is: limiting portion 121 → pressing portion 122 → limiting portion 121 → pressing portion 122; the arrangement sequence of the limiting portion 121 and the pressing portion 122 on the other side wall of the tool holder groove 11 is: pressing portion 122 → limiting portion 121 → pressing portion 122 → limiting portion 121. This ensures that all limiting portions 121 can be alternately arranged on both sides of the tool holder 41, so that the two sides of the tool holder 41 are subjected to cross-force, ensuring that the force on both sides of the tool holder 41 is balanced, and preventing deformation of the tool holder 41 due to excessive force on one side.

[0045] See Figure 2 Optionally, in one embodiment, the box body includes a body portion 10 and a flange portion 20. The box body has a first surface, and the blade groove 11 is formed on the first surface. The flange portion 20 is disposed along the edge of the first surface, and the flange portion 20 is disposed at an angle to the first surface. A reinforcing rib 30 connects the flange portion 20 and the first surface. Specifically, the flange portion 20 is generally used for outer packaging connection. By providing a reinforcing rib 30 between the flange portion 20 and the first surface of the body portion 10, the overall rigidity of the box body can be enhanced, making the box body less prone to deformation. This avoids the problem of the blade 41 coming out of the blade groove 11 due to box body deformation, and enhances the fixation performance of the surgical tool fixation device.

[0046] Furthermore, the number of reinforcing ribs 30 is at least two, and the at least two reinforcing ribs 30 are spaced apart along the edge of the first surface. See also Figure 3 For example, in one embodiment, the box body is provided with five reinforcing ribs 30, which are spaced apart along the edge of the first surface between the first surface and the flange portion 20, thereby further improving the rigidity of the box body.

[0047] See Figure 3 In one embodiment, the housing also has a take-out slot 13, and the blade slot 11 extends through all the take-out slots 13. The width of the take-out slot 13 is greater than the width of the blade slot 11, and the depth of the take-out slot 13 is greater than the depth of the blade slot 11. Thus, when it is necessary to take or put away the blade 41, a finger can be inserted into the take-out slot 13 to easily grasp the blade 41, thereby facilitating the take-out and put-away of the blade 41. Exemplarily, the number of take-out slots 13 is at least two, and the at least two take-out slots 13 are arranged at intervals along the length direction of the blade slot 11. Specifically, the number of take-out slots 13 can be set according to the length of the blade 41, for example, it can be two, three, four or more, etc., and is not limited here.

[0048] See Figure 1In one embodiment, the housing also has a handle groove 14 for accommodating the handle 42 of the surgical instrument, and the handle groove 14 is connected to one end of the blade groove 11. Specifically, the shape of the handle groove 14 matches the shape of the handle 42 of the surgical instrument, thereby better securing the handle 42.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
