In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] This application is based on the inventor's discovery and understanding of the following facts and problems:

[0038] In traditional surgical procedures, surgical instruments need to be manually organized and usually placed individually, which results in low efficiency in organizing surgical instruments and makes it difficult to quickly and accurately find the required surgical instruments during surgery. The surgical instrument holders in the prior art can only realize the placement and organization of a certain number of surgical instruments. For different types of surgeries and different numbers of surgical instruments, the surgical instrument holders in the prior art are not universal and cannot realize fast and accurate management and retrieval of surgical instruments.

[0039] To this end, an embodiment of the utility model designs a surgical instrument holder 100 with an adjustable length of the placement space for the surgical instrument 200, thereby being applicable to the placement and arrangement of different numbers of surgical instruments 200 involved in different types of surgeries, having greater versatility and enabling rapid and accurate management and access to the surgical instruments 200.

[0040] like Figure 2-Figure 3As shown, the surgical instrument 200 includes two symmetrically arranged half bodies hinged by a rotating shaft, a handle is provided on the side of the tails of the two half bodies away from each other, and a finger hole 201 is opened on the handle. The surgical instrument 200 includes two states, namely an open state and a occluded state. When the surgical instrument 200 is in the occluded state, the surgical instrument 200 can be changed from the occluded state to the open state by rotating the handle of one half body to move it away from the handle of the other half body. When the surgical instrument 200 is sterilized, it is necessary to ensure that the surgical instrument 200 is kept in the open state so that the cutting edge 203 of the surgical instrument 200 is separated to ensure the sterilization effect.

[0041] The surgical instrument support 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0042] like Figure 1-Figure 10 As shown, the surgical instrument support 100 according to the embodiment of the present utility model includes: a clamping plate, a base plate 2 and a support rod 3.

[0043] Among them, the two splints extend vertically and are arranged at intervals in the first direction, and a space area for placing the surgical instrument 200 is defined between the two splints. The two splints are arranged on both sides to clamp and fix the surgical instrument 200, that is, the two splints can clamp and set multiple surgical instruments 200 stacked along the first direction, so that the surgical instrument 200 is maintained in an upright posture, which is convenient for quick and accurate management and use of the surgical instrument 200.

[0044] The length direction of the bottom plate 2 extends along the first direction and the two ends of the bottom plate 2 in the length direction are respectively connected to two clamping plates, so that the bottom plate 2 supports the clamping plates on both sides to maintain the stability of the center of gravity of the clamping plates and ensure that the clamping plates stand stably on the horizontal plane.

[0045] The two ends of the support rod 3 are connected to the two clamps respectively, so that the support rod 3 can be fixedly arranged at a certain height above the horizontal plane where the bottom plate 2 is located. The support rod 3 is used to set up the surgical instrument 200, wherein, with reference to Figure 6 and Figure 8 The position of the rotating shaft on the surgical instrument 200 is the position of the shaft joint 202 of the surgical instrument 200. The shaft joint 202 of the surgical instrument 200 is placed on the support rod 3, that is, the support rod 3 is arranged below the surgical instrument 200, supports the surgical instrument 200 from below, and limits the surgical instrument 200 in the horizontal direction to maintain the position and posture of the surgical instrument 200, thereby ensuring the stability of the setting of the surgical instrument 200 and making the posture of the surgical instrument 200 convenient for the operator to take.

[0046] Furthermore, the lengths of the bottom plate 2 and the support rod 3 are adjustable, so that the distance between the two clamps can be adjusted by using the bottom plate 2 with adjustable length, and the support rod 3 can be extended or shortened along with the adjustment of the distance between the clamps. Therefore, when the placement amount of the surgical instrument 200 is less, the lengths of the bottom plate 2 and the support rod 3 can be shortened to ensure that the clamps can stably clamp the surgical instrument 200 on both sides and ensure the posture of the surgical instrument 200 during the placement process. When the placement amount of the surgical instrument 200 is more, the lengths of the bottom plate 2 and the support rod 3 can be extended to reserve enough space for the placement of the surgical instrument 200.

[0047] Specifically, during the placement of the surgical instrument 200, the length of the base plate 2 and the support rod 3 can be lengthened first, and then the surgical instrument 200 can be placed on top of the support rod 3 from one side in turn. After the surgical instrument 200 is placed, the length of the base plate 2 and the support rod 3 can be shortened, so that the distance between the splints on both sides is shortened to the point where the splints on both sides can contact the stacked surgical instruments 200 to clamp and fix the surgical instruments 200, thereby achieving stable placement and arrangement of the surgical instruments 200.

[0048] Therefore, the surgical instrument holder 100 can be used in the placement and arrangement of different numbers of surgical instruments 200 involved in different types of surgeries, and is more versatile, thus achieving rapid and accurate management and access to the surgical instruments 200.

[0049] According to the surgical instrument holder 100 of the embodiment of the utility model, the surgical instrument holder 100 can be used in the process of placing and arranging different numbers of surgical instruments 200 involved in different types of surgeries, has stronger versatility, and realizes fast and accurate management and access to the surgical instruments 200.

[0050] In some embodiments, the surgical instrument 200 needs to be sterilized before and after the operation. During the sterilization process, it is necessary to ensure that the cutting edge 203 of the surgical instrument 200 is partially separated, even if the surgical instrument 200 is in an open state, to ensure the sterilization effect.

[0051] The surgical instrument holder 100 of the embodiment of the utility model can not only assist doctors in quickly and accurately managing and using the surgical instrument 200, but also maintain the posture of the surgical instrument 200 during the cleaning and disinfection process of the surgical instrument 200, so that the surgical instrument 200 is in an open state, thereby ensuring the disinfection effect.

[0052] To this end, the surgical instrument support 100 further includes: a connecting rod 4, such as Figure 1 and Figure 8As shown, the connecting rod 4 is used to pass through the finger hole 201 on one side of the surgical instrument 200 arranged on the surgical instrument bracket 100. At this time, by moving the position of the connecting rod 4, one side half of all the surgical instruments 200 arranged on the support rod 3 can be driven to rotate relative to the other side half, so that all the surgical instruments 200 can be changed from a biting state to an open state, even if the cutting edge 203 of the surgical instrument 200 is partially separated, to ensure the disinfection effect.

[0053] The connecting rod 4 is detachably connected to the two splints, so that after the connecting rod 4 is moved to a suitable position, that is, after the cutting edges 203 of all surgical instruments 200 are partially separated, the connecting rod 4 can be conveniently connected to the splints on both sides, fixing the setting position of the connecting rod 4 while ensuring the stability of the posture of the surgical instrument 200.

[0054] Since the distance between the splints varies with the number of surgical instruments 200 , the length of the connecting rod 4 is adjustable so that the connecting rod 4 can still be connected to the splints on both sides at the same time under different splint distances, thereby ensuring the versatility of the connecting rod 4 .

[0055] Reference Figure 1 and Figure 4 Connecting parts 41 are provided at both ends of the connecting rod 4, and matching connecting parts 13 are provided on the two clamping plates. The connecting parts 41 cooperate with the matching connecting parts 13 to realize a detachable connection between the connecting rod 4 and the clamping plates.

[0056] Among them, the mating connection part 13 includes multiple groups, and the connection part 41 can be matingly connected with any group of mating connection parts 13. Therefore, by controlling the connection part 41 to cooperate with the mating connection parts 13 at different positions, the connecting rod 4 can be fixed at different positions above the support rod 3. For surgical instruments 200 of different sizes and models, a sufficient distance can be set between the connecting rod 4 and the support rod 3 to keep the surgical instrument 200 in an open state, so as to ensure that the cutting edge 203 of the surgical instrument 200 is partially separated to ensure the disinfection effect.

[0057] like Figure 1 and Figure 4 As shown, the connecting part 41 includes an extension rod 41 rotatably connected to the end of the connecting rod 4, and any group of mating connecting parts 13 includes two mating holes arranged opposite to each other on two clamps, wherein the two clamps respectively include inner walls 12 arranged opposite to each other and outer walls 11 arranged opposite to each other, and when the connecting rod 4 is matingly connected to the clamps, the connecting rod 4 passes through the two mating holes, and the extension rod 41 is rotated to a direction parallel to the clamps and mated with the outer walls 11 of the clamps.

[0058] In the process of the connecting rod 4 and the clamping plate being matched and fixed, firstly, the extension rod 41 on one side is rotated to a position parallel to the extension direction of the connecting rod 4, so that the extension rod 41 can pass through the matching hole. After the extension rod 41 passes through the matching hole, one end of the connecting rod 4 is matched with the matching hole, and the extension rod 41 extends to the side of the outer wall 11 of the clamping plate. At this time, the extension rod 41 is rotated again to make the extension rod 41 rotate to a position perpendicular to the connecting rod 4 and parallel to the clamping plate. The extension rod 41 cooperates with the outer wall 11 of the clamping plate to fix one side of the connecting rod 4. At this time, the extension rod 41 on the other side is rotated Move to a position parallel to the extension direction of the connecting rod 4, so that the other side extension rod 41 can pass through the matching hole opened in the other side clamp plate. After the other side extension rod 41 passes through the other side matching hole, the other side end of the connecting rod 4 matches with the other side matching hole, and the other side extension rod 41 extends to the side of the other side clamp plate outer wall 11. At this time, the other side extension rod 41 is rotated again to make the other side extension rod 41 rotate to a position perpendicular to the connecting rod 4 and parallel to the clamp plate, and the other side extension rod 41 matches with the outer wall 11 of the other side clamp plate to fix the other side of the connecting rod 4.

[0059] Further, the length of the connecting rod 4 is adjusted so that the extension rod 41 rotated to a position parallel to the clamp plate can cooperate with the outer wall 11 of the clamp plate, so that the connecting rod 4 is limited in the first direction through the cooperation between the extension rod 41 and the outer wall 11 of the clamp plate to ensure the stability of the setting of the connecting rod 4.

[0060] In some embodiments, the extension rod 41 is 2 cm long, and there are at least two sets of matching connection parts 13 on the two clamping plates, which can respectively match with the connecting rod 4 to fix the connecting rod 4 at a height of 210 cm and 212 cm from the bottom plate. The diameter of the connecting rod 4 is not greater than 1.2 cm.

[0061] In other embodiments, the connecting portion 41 may also include a hook provided at the end of the connecting rod 4, and any group of mating connecting portions 13 may include a slot mating with the hook, and the detachable connection between the connecting rod 4 and the splint may be achieved through the mating of the hook and the slot.

[0062] Reference Figure 1 , Figure 4-Figure 8The bottom plate 2 includes: a first plate portion 21 and a second plate portion 22, the second plate portion 22 is movable along the first direction and flexibly cooperates with the first plate portion 21, and at least a portion of the second plate portion 22 is overlapped above the first plate portion 21. That is to say, there is an overlapping portion between the first plate portion 21 and the second plate portion 22, and in the overlapping portion, the second plate portion 22 is located above the first plate portion 21. By controlling the first plate portion 21 to move relative to the second plate portion 22 along the first direction, or controlling the second plate portion 22 to move relative to the first plate portion 21 along the first direction, the length of the overlapping portion between the first plate portion 21 and the second plate portion 22 in the first direction can be controlled. The longer the length of the overlapping portion in the first direction, the shorter the length of the bottom plate 2 as a whole in the first direction, and the shorter the length of the overlapping portion in the first direction, the longer the length of the bottom plate 2 in the first direction, and then by controlling the length of the bottom plate 2 in the first direction, the distance between the clamps arranged on both sides of the bottom plate 2 in the first direction can be controlled.

[0063] The clamping plate includes a first clamping plate 14 connected to the first plate portion 21 and a second clamping plate 15 connected to the second plate portion 22 .

[0064] like Figure 1-Figure 10 As shown, one of the first plate portion 21 and the second plate portion 22 is provided with a guide groove 212 and the other is provided with a guide protrusion 222. The guide groove 212 cooperates with the guide protrusion 222 to guide the movement of the second plate portion 22 in the first direction. The cooperation between the guide groove 212 and the guide protrusion 222 can guide the movement of the second plate portion 22 during the movement of the second plate portion 22 relative to the first plate portion 21, so that the second plate portion 22 only has the freedom to move along the first direction in the horizontal direction, ensuring that the second plate portion 22 can move stably along the first direction.

[0065] Among them, the guide groove 212 is arranged on the upper surface of the first plate portion 21, the guide groove 212 has an upward opening and an opening toward the second clamping plate 15, the guide protrusion 222 protrudes from the lower surface of the second plate portion 22, the guide protrusion 222 is arranged in the guide groove 212 and can be pushed and pulled along the first direction through the opening of the guide groove 212 toward the second clamping plate 15, and the guide protrusion 222 is connected to the second plate portion 22 through the upward opening of the guide groove 212.

[0066] Reference Figure 1 , Figure 4 and Figure 5One of the second plate portion 22 and the first plate portion 21 is provided with a plurality of matching portions 211 arranged in sequence along the first direction and the other is provided with a limiting portion 221. The limiting portion 221 is suitable for matching with any one of the matching portions 211 to fix the second plate portion 22 at different positions on the first plate portion 21. Through the limiting cooperation between the matching portion 211 and the limiting portion 221, the second plate portion 22 can be limited in the first direction, and then the second plate portion 22 can be fixedly set on the first plate portion 21 to ensure the overall stability of the surgical instrument bracket 100 during use.

[0067] Among them, among the multiple matching parts 211 arranged in sequence along the first direction, there are matching parts 211 that are closer to the corresponding clamping plates on the same side and matching parts 211 that are farther away from the corresponding clamping plates on the same side. When the limiting part 221 matches with the matching part 211 that is farther away from the clamping plates on the same side as the matching part 211, the overlapping part between the first plate part 21 and the second plate part 22 is smaller, the length of the bottom plate 2 in the first direction is long, and the distance between the clamping plates on both sides is farther. When the limiting part 221 matches with the matching part 211 that is closer to the clamping plates on the same side as the matching part 211, the overlapping part between the first plate part 21 and the second plate part 22 is longer, the length of the bottom plate 2 in the first direction is short, and the distance between the clamping plates on both sides is closer.

[0068] In some embodiments, the matching portion 211 and the limiting portion 221 can be respectively arranged on the guide protrusion 222 and the guide groove 212. For example, a plurality of matching portions 211 are arranged in sequence along the first direction on the bottom wall of the guide groove 212, and the limiting portion 221 is arranged on the guide protrusion 222.

[0069] Reference Figure 1 , Figure 2 , Figure 4-Figure 7 , Fig. 9 and Fig.10 The limiting portion 221 is formed as a limiting protrusion 221 which can be moved vertically between the locking position and the unlocking position, and the matching portion 211 is formed as a limiting recess 211. The limiting protrusion 221 is suitable for snap-fitting with any one of the plurality of limiting recesses 211 to fix the second plate portion 22 at different positions on the first plate portion 21.

[0070] Among them, in the unlocked position, the limiting protrusion 221 is separated from the plane where the limiting recess 211 is located in the horizontal direction to ensure that the limiting protrusion 221 can be separated from the limiting recess 211 and ensure that the first plate portion 21 and the second plate portion 22 can move relative to each other in the first direction.

[0071] Specifically, when the distance between the two clamps needs to be changed, that is, when the length of the base plate 2 needs to be changed, the limiting protrusion 221 can be controlled to move from the locked position to the unlocked position, so that the limiting protrusion 221 is disengaged from the limiting recess 211 corresponding to the current position, so that the limiting protrusion 221 remains in the unlocked position. At this time, the first plate portion 21 and the second plate portion 22 can move relative to each other in the first direction, and the overlapping part of the first plate portion 21 and the second plate portion 22 is controlled to increase or shorten, thereby controlling the overall length of the base plate 2 in the first direction until the distance between the two clamps can meet the needs. The limiting protrusion 221 can be controlled to move from the unlocked position to the locked position, and the limiting protrusion 221 automatically cooperates with the limiting recess 211 corresponding to the current position. Through the limiting cooperation between the limiting protrusion 221 and the limiting recess 211, the second plate portion 22 can be limited in the first direction, and then the second plate portion 22 is fixedly set on the first plate portion 21 to ensure the overall stability of the surgical instrument bracket 100 during the use stage.

[0072] like Figure 1 , Figure 2 , Figure 4-Figure 7 As shown, the surgical instrument support 100 further includes a reset member 2211 , wherein the reset member 2211 is connected to the limiting protrusion 221 and is used to drive the limiting protrusion 221 to move toward the locking position.

[0073] That is to say, in the absence of external force, the limiting protrusion 221 can be maintained in the locked position under the action of the reset member 2211, or when the limiting protrusion 221 is in the unlocked position and the external force is lost, the limiting protrusion 221 can automatically return to the locked position under the drive of the reset member 2211. Thus, there is no need for external force to keep the limiting protrusion 221 in the locked position, thereby ensuring the stability of the relative position between the first plate portion 21 and the second plate portion 22.

[0074] Reference Figure 5 The limiting protrusion 221 has a limiting surface 2217 and a guiding surface 2218, the limiting surface 2217 and the guiding surface 2218 are arranged opposite to each other in the first direction, and the angle between the limiting surface 2217 and the first direction is greater than the angle between the guiding surface 2218 and the first direction.

[0075] When the limiting surface 2217 of the limiting protrusion 221 is subjected to a force along the first direction, the force will be decomposed at the limiting surface 2217, wherein part of the force is decomposed into a force that drives the limiting protrusion 221 to move vertically. Under the action of the force, the limiting protrusion 221 moves from the locked position to the unlocked position. Therefore, when the second plate portion 22 moves to one side along the first direction, the second plate portion 22 can be unlocked and driven to move relative to the first plate portion 21 without directly driving the limiting protrusion 221.

[0076] Specifically, refer to Figure 4 and Figure 5 The limiting protrusion 221 is provided on the second plate portion 22, and an installation space having a side opening, an upper opening and a lower opening is formed on the second plate portion 22. The cover plate 2215 is detachably provided at the upper opening through a fixing member 2216, and is used to open or close the upper opening. The limiting protrusion 221 is movably provided in the installation space between a locking position and an unlocking position along the vertical direction. A guide structure 2213 is provided on the lower surface of the cover plate 2215, and a guide matching structure is provided on the upper surface of the limiting protrusion 221. The guide structure 22 13 cooperates with the guide matching structure to guide the vertical movement of the limiting protrusion 221, a reset member 2211 is provided between the limiting protrusion 221 and the cover plate 2215, the reset member 2211 is sleeved on the outer side of the guide structure 2213 and the guide matching structure, when the limiting protrusion 221 is in the locked position, at least a part of it protrudes downward from the lower surface of the second plate portion 22 through the lower opening, and a gripping portion 2212 is provided on the side of the limiting protrusion 221, and the gripping portion 2212 protrudes from the side wall of the second plate portion 22 through the side opening.

[0077] A plurality of limiting recesses 211 are disposed on the upper surface of the first plate portion 21 , a limiting surface 2217 of the limiting protrusion 221 is disposed on the side of the limiting protrusion 221 facing away from the second clamping plate 15 , and a limiting surface 2217 of the limiting protrusion 221 is disposed on the side of the limiting protrusion 221 facing the second clamping plate 15 .

[0078] When the second plate portion 22 is directly driven to move in the direction close to the first clamping plate 14, the limiting surface 2217 contacts and is subjected to force against the wall surface of the limiting recess 211, and the wall surface of the limiting recess 211 can limit the limiting protrusion 221 in the direction of the limiting protrusion 221 facing away from the second clamping plate 15, so that the second plate portion 22 cannot move in the direction close to the first clamping plate 14, that is, the second clamping plate 15 cannot directly move in the direction close to the first clamping plate 14.

[0079] At this time, the limiting protrusion 221 needs to be driven by the gripping portion 2212 protruding from the wall of the second plate portion 22 to move from the locked position to the unlocked position, and when the limiting protrusion 221 is at the unlocked position, the second clamping plate 15 is moved toward the direction close to the first clamping plate 14.

[0080] When driving the second plate portion 22 to move in the direction away from the first clamping plate 14, the guide surface 2218 contacts the wall surface of the limiting recess 211 and is subjected to force. The force will be decomposed at the limiting surface 2217, wherein part of the force is decomposed into a force that drives the limiting protrusion 221 to move vertically upward. Under the action of the force, the limiting protrusion 221 moves from the locked position to the unlocked position. The second plate portion 22 is unlocked and can move in the direction away from the first clamping plate 14, that is, the second clamping plate 15 can directly move in the direction away from the first clamping plate 14.

[0081] Combination Figure 1 , Figure 3 , Figure 6 , Figure 8 , Fig. 9 and Fig.10 In the illustrated embodiment, one of the first plate portion 21 and the second plate portion 22 is provided with a limit groove 213 opening toward the second direction and the other is provided with a limit block 223. The second direction is perpendicular to the first direction in the horizontal direction. The limit block 223 is plugged into and fits with the limit groove 213 so as to be movable along the first direction. The cooperation between the limit groove 213 and the limit block 223 can limit the second plate portion 22 in the vertical direction, thereby ensuring that the relative position of the second plate portion 22 and the first plate portion 21 is stable and the second plate portion 22 can only move relative to the first plate portion 21 along the first direction.

[0082] The limiting block 223 and the limiting groove 213 can be respectively disposed on the guide protrusion 222 and the guide groove 212, Figure 1 , Figure 3 , Figure 6 , Figure 8 , Fig. 9 and Fig.10 The limiting block 223 is disposed on the guide protrusion 222 and protrudes from the side wall of the guide protrusion 222 , and the limiting groove 213 is disposed on the guide groove 212 and on the side wall of the guide groove 212 .

The support member 5 is supported and arranged between the second plate portion 22 and the conduit 31 to enhance the strength of the support member 5 and prevent the support member 5 from being deformed due to the excessive weight of the surgical instrument 200. In addition, by arranging the support member 5 between the second plate portion 22 and the conduit 31, it is also possible to prevent the setting of the support member 5 from affecting the normal extension and retraction of the base plate 2 and the support member 5.

[0085] Reference Figure 1 and Fig. 9 The surgical instrument support 100 also includes an anti-slip structure, which can limit the first splint 14 and the second splint 15 in a direction in which the first splint 14 and the second splint 15 move away from each other, thereby preventing the second plate portion 22 from detaching from the first plate portion 21.

[0086] Specifically, the anti-slip structure includes a first anti-slip surface 7 and a second anti-slip surface 8. The first anti-slip surface 7 is arranged on the first plate portion 21 and / or the guide rod 32, and the first anti-slip surface 7 is arranged toward the first splint 14. The second anti-slip surface 8 is arranged on the second plate portion 22 and / or the guide tube 31, and the second anti-slip surface 8 is arranged toward the second splint 15. When the second splint 15 moves to the farthest distance relative to the first splint 14, the first anti-slip surface 7 and the second anti-slip surface 8 are stopped and matched.
