Description

Technical Field

[0001] This invention relates to a device for storing surgical instruments. Background Technology

[0002] Medical surgeries typically involve a variety of surgical instruments, and the types and / or quantities of instruments required vary depending on the specific surgery. Clinically, after cleaning, surgical instruments are packaged in cloth bags and stored in different instrument packs, which are then sterilized at high temperatures before being carried and used. The instrument packs do not have specific markings for each instrument, and after surgery, the instruments in the packs are manually checked against a list, which is inconvenient and labor-intensive. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology by providing a surgical instrument organization device for packaging and placing surgical instruments, which can generate cavities that match the surgical instruments, thereby facilitating the corresponding counting of instruments.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A surgical instrument placement device includes a needle mold unit, which includes a support foot, two needle positioning hole plates, and a plurality of shaping needles. The two needle positioning hole plates are an upper needle positioning hole plate and a lower needle positioning hole plate arranged vertically and parallel to each other on the support foot. The two positioning hole plates are densely covered with corresponding positioning needle holes. The shaping needles are configured to restrict their movement on the positioning needle holes. The shaping needles have an extended portion that extends beyond the distance between the two needle positioning hole plates. The two ends of the shaping needles respectively pass through the corresponding needle positioning hole plates. There is an overhead space below the lower needle positioning hole plate for the shaping needles to extend into. The shaping needles are equipped with a damping mechanism that allows the shaping needles to be held in any position.

[0005] Preferably, the damping mechanism includes a damping orifice plate, which is slidably fitted on the support foot. The damping orifice plate is disposed between two needle positioning orifice plates, and there is a gap between the damping orifice plate and the two needle positioning orifice plates. An elastic member is provided on the support foot, which elastically abuts against the side wall of the damping orifice plate. An elastic member is provided on one side of the damping orifice plate so that the damping orifice plate moves to one side under the elastic force of the elastic member. The damping orifice plate is provided with needle holes that correspond one-to-one with the positioning needle holes on the needle positioning orifice plate. Under the elastic force of the elastic member, the wall of the needle hole abuts against the shaping needle and forms a damping fit.

[0006] Preferably, the diameter of the needle hole is larger than the diameter of the shaping needle, the damping plate has a damping state in which the hole wall of the needle hole abuts against the shaping needle and an unlocked state in which the needle hole and the positioning needle hole are aligned to allow the shaping needle to slide freely, and the support foot has a limiting wall for the damping plate to abut against to stop the damping plate in the unlocked state.

[0007] Preferably, the elastic component includes a pressing member, an adjusting screw, and a spring. The support foot is provided with a mounting guide hole for the pressing member to slide. The adjusting screw is threaded into the opening of the mounting guide hole, and the pressing member is restricted to slide within the mounting guide hole. One end of the pressing member extends out of the mounting guide hole and abuts against the damping plate. The spring is provided between the other end of the pressing member and the adjusting screw.

[0008] Preferably, the support foot is also provided with a protective base plate, which is located below the lower needle positioning hole plate, and forms the overhead space between the protective base plate and the lower needle positioning hole plate.

[0009] Preferably, the bottom end of the shaping needle has a flat, anti-detachment head end that cooperates with the positioning needle hole stop of the lower needle positioning plate, and the top end of the shaping needle can pass through the positioning needle hole of the needle positioning plate. The flat, anti-detachment head end cooperates with the stop of the protective base plate.

[0010] Preferably, an upper protective plate is also provided, which is detachably covered on the top of the support foot, forming a space between the upper protective plate and the upper needle positioning hole plate to accommodate the protruding part of the shaping needle.

[0011] Preferably, it includes multiple needle mold units, which can be stacked and stored, and can be laid flat and disassembled and spliced.

[0012] Preferably, the support foot includes a first support foot and a second support foot respectively arranged on a pair of opposite sides of the needle positioning hole plate. Two first support feet and two second support feet are provided on one side of the needle positioning hole plate. The first support feet and the second support feet are staggered. The two first support feet are located between the two second support feet, and the two first support feet can be inserted into the gap between the two second support feet to form a splice.

[0013] Preferably, the bottom ends of the first and second support feet have narrow support feet, and the tops of the first and second support feet have stepped grooves into which the narrow support feet can be inserted.

[0014] The surgical instrument placement device provided by this invention is used as follows: The extended portion of the positioning pin extends beyond the upper pin positioning hole plate, thus forming a floating placement surface at the tip of the positioning pin. Under the action of a damping mechanism, the positioning pin can be held in the corresponding position. The instrument is pressed against the placement surface, and a certain force is applied to push the instrument down, pressing down the tip of the positioning pin supported on the instrument. This creates a positioning recess (i.e., a positioning cavity) on the placement surface formed by the positioning pin, matching the shape of the instrument, and this recess can be maintained. This provides positioning for the instrument, facilitating its placement and high-temperature, high-pressure sterilization. More importantly, the positioning recess on the surgical instrument placement device matches the contour of the instrument, allowing for one-to-one instrument counting and retrieval during instrument recovery, making it more intuitive and convenient. The surgical instrument placement device forms positioning recesses along with the instruments and can be restored, better adapting to different instrument packs and exhibiting good versatility.

[0015] The present invention will now be further described with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0017] See appendix Figures 1-6 The present invention discloses a surgical instrument storage device, including a needle mold unit 1. For the convenience of disinfection and use, a surgical instrument storage device may include at least two sets of needle mold units 1 (two sets of needle mold units are shown in this specific embodiment) to achieve a miniaturized design of a single needle mold unit. Multiple needle mold units 1 can be stacked and stored to reduce the area occupied by the surgical instrument storage device and facilitate placement into a disinfection device for disinfection. In use, multiple needle mold units can be laid flat and can be disassembled and spliced.

[0018] The needle mold unit 1 includes a support foot 11, two needle positioning plates 12 and 13, and several shaping needles 14. The two needle positioning plates 12 and 13 are respectively the upper needle positioning plate 12 and the lower needle positioning plate 13, which are arranged vertically and parallelly on the support foot 11. The two positioning plates 12 and 13 are densely covered with corresponding positioning needle holes. The shaping needles 14 are configured to be restricted to move within the positioning needle holes 11. The shaping needles 14 have an extended portion that extends beyond the distance between the two needle positioning plates 12 and 13. The length of the extended portion can be set as needed. The two ends of the shaping needles 14 pass through the corresponding needle positioning plates 12 and 13, respectively. There is an overhead space 15 below the lower needle positioning plate 13 for the shaping needles to extend into. The shaping needles 14 are equipped with a damping mechanism to hold the shaping needles 14 in any position. The support foot adopts a design of multiple independent units to reduce unnecessary solid parts and reduce the overall weight of the device. The support foot 11 includes a support body 111, on which a positioning slot 1111 is provided. The needle positioning hole plates 12 and 13 are inserted into the slot 1111. The support body is provided with a fixing shaft 112, which is inserted into the shaft hole of the needle positioning hole plates 12 and 13 for fixing.

[0019] The damping mechanism includes a damping orifice plate 16, which is slidably fitted on the support leg 11. The damping orifice plate 16 is located between two needle positioning orifice plates 12 and 13, and there is a gap between the damping orifice plate 16 and the two needle positioning orifice plates 12 and 13. This gap provides space for the damping orifice plate 16 to slide and facilitates the entry of high-temperature steam for sterilization. An elastic member 17 is provided on the support leg 11, which elastically abuts against the side wall of the damping orifice plate 16. An elastic member 17 is provided on one side of the damping orifice plate 16 so that the damping orifice plate 16 moves to one side under the elastic force of the elastic member 17. The damping orifice plate 16 has needle holes 161 that correspond one-to-one with the positioning needle holes on the needle positioning orifice plates 12 and 13. Under the elastic force of the elastic member 17, the wall of the needle hole of the damping orifice plate 16 abuts against the shaping needle 14 and forms a damping fit. A row of through holes 161 on the damping orifice plate 16, perpendicular to the sliding direction of the damping orifice plate 16, can be formed into a strip-shaped hole to reduce the weight of the damping orifice plate 16. This damping mechanism uses the damping orifice plate to elastically press against the shaping needle to generate damping force; it has a simple structure and is easy to manufacture. The support body has a movable insertion port 1112 for inserting the damping orifice plate, and the damping orifice plate 16 has a slotted hole 162. The slotted hole 162 and the fixed shaft 112 cooperate to achieve positioning and guidance. The diameter of the needle hole is larger than the diameter of the shaping needle. The damping plate 16 has a damping state where the wall of the needle hole 161 abuts against the shaping needle 14, and an unlocking state where the needle hole 161 is aligned with the positioning needle hole to allow the shaping needle 14 to slide freely. The larger needle hole diameter design means that when the needle hole and the positioning needle hole are aligned, the shaping needle is no longer restricted by the damping plate. The shaping needle 14 can fall back to its original position under the action of gravity, which makes it easier to reset the shaping needle for the placement of the instrument. The support foot 11 has a limiting wall for the damping plate 16 to abut against to stop the damping plate 16 in the unlocked state. In this specific embodiment, the wall of the movable insertion port is used to stop the damping plate, which makes it easier to press the damping plate 16 into the unlocked state and maintain it. During operation, the damping orifice plate 16 is pushed against one side wall opposite the elastic member. The damping orifice plate is usually designed to be thin to reduce the overall weight of the device. Therefore, during operation, the damping orifice plate can be pushed with the help of corresponding pads, or the edge of the damping orifice plate can be thickened by adopting an arc design to avoid cutting the operator; or a top pressing module can be fixed on the two needle positioning orifice plates. The top pressing module includes a fixed mounting block, which is fixed on the needle positioning orifice plate. The mounting block is equipped with a top pressing screw. The top pressing screw can be rotated in and out by a tool. After the top pressing screw is rotated in, it can push the damping orifice plate to the unlocked state, etc.

[0020] The elastic member 17 includes a pressing member 171, an adjusting screw 172, and a spring 173. A mounting guide hole for the pressing member 171 to slide is provided on the support foot 11. The adjusting screw 172 is threaded into the opening of the mounting guide hole, restricting the pressing member 171 to slide within the mounting guide hole. One end of the pressing member 171 extends out of the mounting guide hole and abuts against the damping plate 16. The spring 173 is disposed between the other end of the pressing member 171 and the adjusting screw 172. In this specific embodiment, the mounting guide hole is formed on an independent cylindrical shell, which is assembled into the mounting hole of the support foot 11. That is, the elastic member can be a spring pin to achieve component modularity and facilitate installation on the support foot. The elastic abutment force of the elastic member against the damping plate is adjustable, thus adjusting the contact pressure of the damping plate on the shaping pin, i.e., adjusting the damping force.

[0021] To prevent deformation and potential damage to the shaping pin due to pressure during carrying and use, a protective base plate 18 is provided on the support foot 11. The protective base plate 18 is located below the lower needle positioning hole plate 13, forming the overhead space 15 between the protective base plate 18 and the lower needle positioning hole plate 13. The protective base plate 18 protects the bottom of the shaping pin 14. Under the premise of reliable protection, the protective base plate can be partially hollowed out to achieve overall weight reduction of the device. Similarly, an upper protective plate 19 is also provided. The upper protective plate 19 is detachably covered on the top of the support foot 11, forming an air gap between the upper protective plate 19 and the upper needle positioning hole plate 12 to accommodate the protruding part of the shaping pin 14. During carrying and sterilization, the upper protective plate covers the top of the shaping needle to protect it. When in use, the upper protective plate is removed to facilitate the retrieval and placement of medical instruments. Under the premise of reliable protection, the upper protective plate can be partially hollowed out to reduce the overall weight of the device. With multiple needle mold units, the multiple needle mold units are stacked when the device is stored. Therefore, the surgical instrument storage device in a surgical instrument kit only needs to be equipped with one upper protective plate.

[0022] In this specific embodiment, the bottom end of the shaping needle 14 has an anti-detachment flat head end 141 that cooperates with the positioning needle hole stop of the lower needle positioning hole plate 13. The top end of the shaping needle 14 can pass through the positioning needle hole of the needle positioning hole plates 12 and 13, and the anti-detachment flat head end 141 cooperates with the stop of the protective base plate 18. In this way, the top end of the shaping needle can freely pass through the positioning needle hole. Under the restriction of the protective base plate, the shaping needle is restricted from detaching from the needle positioning hole plate in the downward direction. In the upward direction, the shaping needle is also restricted from detaching from the needle positioning hole plate under the restriction of the anti-detachment flat head end. This design facilitates the assembly of the shaping needle and subsequent maintenance and replacement. The protective base plate can be installed on the support foot using fasteners.

[0023] In this specific embodiment, the support foot 11 includes a first support foot 11-1 and a second support foot 11-2 respectively arranged on a pair of opposite sides of the needle positioning hole plate. Two first support feet 11-1 and two second support feet 11-2 are provided on one side of the needle positioning hole plate. The first support feet 11-1 and the second support feet 11-2 are staggered, with the two first support feet 11-1 located between the two second support feet 11-2, and the two first support feet 11-1 can be inserted between the two second support feet 11-2 to form a splice (e.g., ...). Figure 4As shown, this staggered arrangement of the support legs forms an interlocking structure, resulting in a simple design that controls the overall weight of the surgical instrument placement device. Steps are formed at the bottom of the first support leg 11-1 and the second support leg 11-2 for the protective base plate 18 to rest on, facilitating its positioning and installation. Narrow support ends 1110 are located at the bottom of the first and second support legs 11-1. To facilitate the stacking and positioning of the two sets of needle mold units, stepped grooves 1113 are provided at the top of the first and second support legs 11-1 and the second support leg 11-2 for the narrow support ends 1110 to be inserted. Similarly, a protrusion for inserting the stepped groove 1113 is also provided on the upper protective plate 19, making the overall structure simple and compact, thus controlling the overall weight of the surgical instrument placement device. To control the overall weight of the surgical instrument placement device, those skilled in the art can also control it by adjusting the materials and dimensions of the components. This control method can be achieved by those skilled in the art based on limited experiments and existing technology.
