Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a human tissue surgery device. Background Art

[0002] For human tissue surgical devices on the market, for example, bone grafting is a surgical procedure that transplants bone tissue to the bone defect site in the patient's body that needs to be strengthened or fused. It is often used for bone defects, nonunion of fractures, filling of cavities after scraping of bone diseases or bone tumors, spinal and joint fusion, etc.

[0003] Autologous bone transplantation, which is commonly used in clinical practice, has many advantages, such as good tissue compatibility, no transplant rejection reaction, strong bone induction, etc., and has a good effect in promoting bone fusion. Common bone removal sites for autologous bone transplantation include the ilium, tibia, upper fibula and ribs. Autologous bone transplantation is to remove the bone from these parts of the patient's body, and then return it to the patient's bone defect after processing. Taking autologous iliac bone transplantation as an example, it is usually necessary to make a skin and soft tissue incision of several centimeters long, and a relatively extensive subperiosteal stripping, and then use an osteotome to open a window on the iliac bone or directly chisel the iliac bone.

[0004] However, traditional bone tissue surgical equipment also has some defects. The first step of traditional bone tissue surgical equipment is to cut the skin soft tissue with a scalpel, the second step is to drill holes with other bone drills, and the third step is to use a special sampling device to cut, grind and drill the cancellous bone. Since the second and third steps use independent equipment, and each of the equipment used in these two steps is almost disposable, the existing bone tissue surgical process equipment cost is relatively high. At the same time, the process of replacing equipment also reduces the surgical efficiency of the bone tissue surgical process. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the above-mentioned shortcomings and deficiencies of the prior art, the utility model provides a human tissue surgical device, which solves the technical problems in the prior art that the equipment cost of the bone tissue surgical process is high and the process of replacing the equipment also reduces the surgical efficiency of the bone tissue surgical process.

[0007] (II) Technical solution

[0008] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include:

[0009] In the first aspect, the utility model provides a human tissue surgical device, comprising a handle, a drill tool detachably connected to one end of the handle, and a locking assembly connected to the handle to limit the position of the drill tool relative to the handle; the drill tool comprises a connecting portion extending into the handle; the drill tool is arranged in a plurality of functional models, and each functional model of the drill tool comprises a connecting portion with the same structure; a card slot is provided on the connecting portion; the locking assembly comprises a floating rod, which is slidably connected to the handle along its own axial direction, and the axial direction of the floating rod intersects with the axial direction of the connecting portion; a clearance groove is provided on the floating rod to make room for sliding when the connecting portion slides; a card block is formed on the floating rod along the clearance groove on at least one side of the axial direction of the connecting portion; the floating rod can slide in the card slot, so that the floating rod can switch between an unlocked state when the clearance groove slides to a position corresponding to the card slot, and a locked state when the card block slides to a position corresponding to the card slot.

[0010] (III) Beneficial effects

[0011] The beneficial effects of the utility model are as follows: the human tissue surgical device of the utility model, since the drill tool and the handle are connected in a detachable manner, different types of drill tools can be flexibly replaced according to needs. For example, when it is necessary to drill a hole in a bone, the drill tool is replaced with a hole drill; when it is necessary to take a sample, the drill tool is replaced with a sampling drill. In this way, the hole-making process and the sampling process will share the same handle, thereby reducing the cost of disposable equipment.

[0012] Furthermore, the drilling tools all include connecting parts of the same type, thereby ensuring the interchangeability of the drilling tools and improving the efficiency of disassembly, assembly and replacement of the drilling tools.

[0013] In the locking structure of the utility model, when the floating rod slides to a certain position, the clearance groove is aligned with the sliding path of the connecting part, allowing the connecting part to slide freely. At this time, the card block does not cooperate with the card slot, so there is no locking effect; when the floating rod slides to another position, the card block will enter and lock in the card slot. At this time, due to the cooperation between the card block and the card slot, the connecting part is locked and cannot slide along its axial direction.

[0014] The user can switch the unlocking and locking states of the floating rod by operating the floating rod. Under the action of the locking component of this structure, the drill can be quickly and efficiently disassembled and assembled on the handle, thereby improving the efficiency of the operation.

[0015] At the same time, without actively operating the floating rod to make it slide axially, once the slot and the block cooperate, the drill bit will not detach from the handle unless the handle, the connecting part and the locking assembly structure are damaged, thereby greatly improving the safety of the surgical process.

DETAILED DESCRIPTION

[0025] In order to better explain the present invention and facilitate understanding, the following Figure 1-7 , the utility model is described in detail through specific implementation methods.

[0026] Embodiment 1:

[0027] Reference Figure 1-Figure 7 An embodiment of the utility model provides a human tissue surgical device, comprising a handle 1, a drill 2 detachably connected to one end of the handle 1, and a locking assembly 3 connected to the handle 1 to limit the position of the drill 2 relative to the handle 1; the drill 2 comprises a connecting portion 21 extending into the handle 1, and the connecting portion 21 can be locked by the locking assembly 3; the drill 2 is configured to have multiple functional models including a hole drill and a sampling drill, and each model of the drill 2 comprises a connecting portion 21 with the same structure.

[0028] In this embodiment, since the drill tool 2 and the handle 1 are connected in a detachable manner, different types of drill tools 2 can be flexibly replaced according to needs. For example, when it is necessary to drill a hole in the bone, the drill tool 2 is replaced with a hole drill; when sampling is required, the drill tool 2 is replaced with a sampling drill. In this way, the hole drilling process and the sampling process will share the same handle 1, thereby reducing the cost of disposable equipment.

[0029] Furthermore, the drilling tools 2 all include the same type of connecting parts 21 , which ensures the interchangeability of the drilling tools 2 and improves the efficiency of disassembly, assembly and replacement of the drilling tools 2 .

[0030] In this embodiment, a card slot 201 is provided on the connecting part 21; the locking assembly 3 includes a floating rod 31 which is slidably connected to the handle 1 along its own axial direction, and the axial direction of the floating rod 31 intersects with the axial direction of the connecting part 21, and a clearance groove 301 is provided on the floating rod 31 to make sliding space for the connecting part 21 when sliding; on the floating rod 31, a card block 302 is formed on at least one side of the axial direction of the connecting part 21 along the clearance groove 301; the floating rod 31 can slide in the card slot 201, so that the floating rod 31 can switch between an unlocked state when the clearance groove 301 slides to a position corresponding to the card slot 201, and a locked state when the card block 302 slides to a position corresponding to the card slot 201.

[0031] In this embodiment, the connecting portion 21 is an end member of the drilling tool 2 , and is provided with slots 201 , which are used to cooperate with the blocks 302 on the floating rod 31 to achieve the locking or unlocking function.

[0032] The floating rod 31 is a rod body connected to the handle 1, for example, inserted into a sleeve on the handle 1 to establish a sliding connection between the floating rod 31 and the handle 1, and its axis direction intersects with the axis direction of the connecting portion 21. This means that the floating rod 31 can move in a direction different from that of the connecting portion 21.

[0033] There is a clearance groove 301 on the floating rod 31, and this groove is to provide enough space for the connecting part 21 when sliding along its own axis direction. In other words, when the connecting part 21 needs to move, this clearance groove 301 can prevent the floating rod 31 from hindering its movement.

[0034] On the floating rod 31, a block 302 is formed along the make way groove 301 on at least one side of the axial direction of the connecting part 21, and the block 302 can cooperate with the slot 201 on the connecting part 21. Since the fixed rod and the block 302 do not have the freedom to slide along the axial direction of the connecting part 21, the block 302 can limit the position of the connecting part 21 by cooperating with the slot 201, thereby enabling the drilling tool 2 to be connected to the handle 1.

[0035] The sliding movement of the floating rod 31 in the slot 201 allows it to switch between two states:

[0036] Unlocked state: When the floating rod 31 slides to a certain position, the clearance groove 301 is aligned with the sliding path of the connecting part 21, allowing the connecting part 21 to slide freely. At this time, the block 302 does not cooperate with the slot 201, so there is no locking effect.

[0037] Locked state: When the floating rod 31 slides to another position, the block 302 enters and is locked in the slot 201. At this time, due to the cooperation between the block 302 and the slot 201, the connecting portion 21 is locked and cannot slide along its axial direction.

[0038] The user can operate the floating lever 31 , which may be rotated, pushed or in other ways, to switch the floating lever 31 between the unlocked and locked states.

[0039] When the connection part 21 needs to slide freely, the floating rod 31 is placed in an unlocked state; when the position of the connection part 21 needs to be fixed, the floating rod 31 is placed in a locked state.

[0040] Under the action of the locking assembly 3 of this structure, the drill 2 can be quickly and efficiently assembled and disassembled from the handle 1, thereby improving the efficiency of the operation.

[0041] At the same time, without actively operating the floating rod 31 to make it slide axially, once the slot 201 cooperates with the block 302, the drill 2 will not detach from the handle 1 if the handle 1, the connecting part 21 and the locking assembly 3 are not damaged, thereby greatly improving the safety of the surgical procedure.

[0042] Specifically, the clearance groove 301 can be an annular groove formed on the floating rod 31. After the annular groove is formed, a clamping block 302 will naturally be formed on the columnar floating rod 31, thereby reducing the structural cost of the floating rod 31. The clamping groove 201 can also be an annular groove formed on the connecting portion 21.

[0043] In this embodiment, one end of the floating rod 31 extends out of the handle 1 to form a pressing portion 303, and the locking assembly 3 also includes a reset member 32, which maintains the force applied to the floating rod 31 to reset from the unlocked state to the locked state; the reset member 32 includes a compression spring, one end of the spring abuts against the inner wall of the handle 1, and the other end of the spring abuts against the main body of the floating rod 31 located in the inner cavity of the handle 1.

[0044] In this embodiment, one end of the floating rod 31 extends out of the handle 1 to form a user-friendly pressing portion 303. The pressing portion 303 allows the user to overcome the force of the reset member 32, such as a compression spring, by a simple pressing action to switch the floating rod 31 from the locked state to the unlocked state.

[0045] The effect of the reset member 32 is to ensure that the floating rod 31 can automatically return to the locked state when not subjected to external force. This is achieved by applying a continuous force to the floating rod 31.

[0046] In this embodiment, the reset member 32 is a compression spring. One end of the spring abuts against the inner wall of the handle 1 , and the other end abuts against the body of the floating rod 31 located in the inner cavity of the handle 1 .

[0047] When the floating rod 31 is pressed to the unlocked state by the user, the spring will be compressed and store energy. Once the user releases the pressing force, the spring will release the stored energy and push the floating rod 31 back to the locked state.

[0048] When the user needs to unlock the connecting portion 21, the user can overcome the force of the spring by pressing the pressing portion 303 of the floating rod 31, so that the floating rod 31 slides to the unlocked state. In this process, the block 302 will leave the slot 201, allowing the connecting portion 21 to slide freely along its axial direction.

[0049] When the user releases the pressing force, the spring pushes the floating rod 31 back to the locked state. In this process, the block 302 reenters the slot 201 to lock the position of the connecting portion 21.

[0050] This locking assembly 3 realizes the locking and unlocking functions of the connecting portion 21 through the coordinated action of the floating rod 31, the pressing portion 303, the compression spring and the card slot 201. The user can switch the state of the floating rod 31 by a simple pressing operation, thereby conveniently controlling the movement of the connecting portion 21. At the same time, the introduction of the reset member 32 ensures that the floating rod 31 can automatically return to the locked state when no external force is applied, thereby improving the stability and reliability of the system.

[0051] In this embodiment, the human tissue surgical device also includes a rotating drive member 4 supported in the inner cavity of the handle 1, and a connecting column 25 extends from the connecting portion 21 near the tail end of the rotating drive member, and the driving end of the rotating drive member 4 is detachably driven and connected to the connecting column 25; the connecting column 25 and the driving end of the rotating drive member 4 are socketed along the axial direction of the connecting column 25 to establish a detachable driving connection relationship; the connecting column 25 and the rotating drive member 4 have torsional ridges that cooperate with each other.

[0052] In this embodiment, the rotary drive member 4 is supported in the inner cavity of the handle 1 to provide rotary power. The connecting column 25 establishes a detachable driving connection relationship with the rotary drive member 4 to drive the drilling tool 2 to realize the rotation function.

[0053] The driving end of the rotary drive member 4 is detachably connected to the connecting post 25 through a specific structure. This design allows the connecting post 25 to be easily separated or connected to the rotary drive member 4 when needed.

[0054] For example, a sleeve connection is adopted, where the connecting column 25 and the driving end of the rotating driving member 4 are sleeved along the axial direction of the connecting column 25. This sleeve connection ensures the stability of the connection and the accuracy of the transmission.

[0055] The connecting column 25 and the rotating drive member 4 are designed with torsional ribs that cooperate with each other. The function of the torsional ribs is to ensure that the torque can be reliably transmitted between the two and to ensure that there is no slippage or looseness when transmitting the rotating power. At the same time, the torsional ribs also provide a guiding function for easy disassembly and installation.

[0056] Specifically, the side surface of the connecting column 25 can be symmetrically milled with a plurality of planes along its own axis, and the driving end of the rotating driving member 4 is set as a sleeve 24 that matches the shape of the connecting column 25. Along the circumferential direction of the connecting column 25, the edge of the milled plane will form a torsion ridge to ensure reliable torque transmission and provide a guide for the installation process. At the same time, the centrally symmetrical planes on the connecting column 25 also enable the connecting column 25 to cooperate with the sleeve 24 in multiple directions, thereby improving the assembly convenience of the drilling tool 2.

[0057] Specifically, four planes may be milled on the connecting column 25 to reduce processing costs.

[0058] During installation, it should be ensured that the torsion ridges of the connecting column 25 and the rotating drive member 4 are correctly aligned and tightly matched. During disassembly, the two can be easily separated using appropriate tools or methods.

[0059] This design not only ensures the stability of the connection and the accuracy of the transmission, but also facilitates the disassembly and installation of the connecting column 25. In practical applications, this connection method can meet the surgical device's requirements for the rotation function of the drill 2 and improve the efficiency and safety of the surgery.

[0060] The rotating driving member 4 is a motor with adjustable speed to improve the flexibility of use of the drilling tool 2.

[0061] Furthermore, the rotary drive member 4 is driven by a constant current, that is, the current flows through the rotary drive member 4 only after passing through the constant current drive board, so as to ensure the rotation stability of the rotary drive member 4 .

[0062] And it can adopt the form of button-type speed regulation and the form of button-type opening, and the speed regulation button and the speed indicator light are both arranged on the outside of the handle 1.

[0063] The speed control button, the main switch and the speed indicator light can be supported by an annular frame, which is sleeved on the outside of the rotating drive member 4 and supported on the inner wall of the handle 1 to avoid interference between the above structures and the rotating drive member 4.

[0064] In this embodiment, the drilling tool 2 also includes a drill bit 22 and a middle part 23, and the drill bit 22 and the connecting part 21 are connected to the two ends of the middle part 23; a transportation area 202 is formed on the middle part 23 to transport materials from the drill bit 22 to the connecting part 21 when the drilling tool 2 is drilling.

[0065] In this embodiment, the drill bit 22 is the front end of the drill tool 2, which is used to directly contact and cut or drill into human tissue. According to the difference in parameters such as the hardness of the opening area and the opening area, the drill tool 2 is set to a suitable structure, such as a round drill bit 22, a double-edged drill bit 22, and a three-edged drill bit 22. The middle part 23 is located between the drill bit 22 and the connecting part 21, and is a bridge connecting the two. At the same time, it also transmits the torque obtained by the connecting part 21 to the drill bit 22.

[0066] A transport area 202 is formed on the middle portion 23, which is used to transport the cut or drilled materials, such as tissue fragments, blood, bone, etc., from the drill bit 22 to the connecting portion 21 when the drill 2 is drilling. This design helps to keep the surgical area clean and prevent material blockage or affect the progress of the operation. At the same time, when the drill 2 is a sampling drill, the transport area 202 is also used to transport the sample outside the human body.

[0067] Embodiment 2:

[0068] Reference Figure 1-Figure 4 , Figure 6 In addition to all the technical solutions of the above embodiments, the embodiments of the present utility model further have the following technical solutions:

[0069] The handle 1 includes a first body 11 and a second body 12 which are detachably connected to each other. The inner cavity of the first body 11 forms a sampling chamber 101. A through hole is provided on the side wall of the first body 11 away from the second body 12. A transport area 202 is formed on the middle part 23, and the transport area 202 extends from the through hole to the sampling chamber 101. The handle 1 also includes a sleeve 5 supported on the first body 11. The sleeve 5 is sleeved on the outside of the transport area 202 located outside the first body 11, and the sleeve 5 is connected to the sampling chamber 101. An observation window 102 is provided on the side wall of the first body 11 corresponding to the sampling chamber 101.

[0070] In this embodiment, the handle 1 includes two detachably connected parts: a first body 11 and a second body 12. This design allows the handle 1 to be easily disassembled and assembled when necessary, which is convenient for cleaning, maintenance and replacement of parts. For example, the locking assembly 3 is arranged at the detachable connection between the two, so that the assembly and maintenance of the locking assembly 3 can be more conveniently achieved.

[0071] The inner cavity of the first body 11 forms a sampling chamber 101. The sampling chamber 101 is used to collect materials, such as tissue samples, blood, and aggregates, that are transferred from the drill bit 22 of the drilling tool 2 through the transport area 202. A through hole is provided on the side wall of the first body 11 away from the second body 12. The through hole provides a passage for the transport area 202, so that the materials can enter the handle 1 from the drill bit 22 of the drilling tool 2, and finally reach the sampling chamber 101.

[0072] The transport area 202 of the middle part 23 starts from the drill bit 22 of the drilling tool 2 and extends into the sampling bin 101 through the through opening. When the drilling tool 2 is drilling, the transport area 202 is responsible for transporting the material from the drill bit 22 to the connecting part 21 and finally into the sampling bin 101. The handle 1 also includes a sleeve 5, which is supported on the first body 11 and sleeved on the outside of the transport area 202 located outside the first body 11. The function of the sleeve 5 is to provide a protective barrier for the transport area 202 to prevent the material from leaking or overflowing during transportation. At the same time, the sleeve 5 is connected to the sampling bin 101 to ensure that the material can smoothly enter the sampling bin 101.

[0073] The first body 11 has an observation window 102 on the side wall corresponding to the sampling chamber 101. The observation window 102 allows the user to directly observe the situation in the sampling chamber 101, such as the collection amount and state of the material, without opening the handle 1. This design improves the convenience and efficiency of the operation.

[0074] The design fully considers the actual needs during the operation. Through the coordinated action of the detachably connected first body 11 and second body 12, sampling chamber 101, through-hole, transport area 202, sleeve 5 and observation window 102, the handle 1 can conveniently and efficiently collect and process the materials transmitted from the drill bit 22 of the drilling tool 2. This design not only improves the convenience and efficiency of the operation, but also ensures the safety and accuracy of the operation.

[0075] The handle 1 further includes a partition 15 , which is supported on the side wall of the first body 11 . The connecting portion 21 penetrates the partition 15 and cooperates with the locking assembly 3 to prevent the material in the sampling chamber 101 from leaking toward the locking assembly 3 .

[0076] The partition 15 is supported on the side wall of the first body 11, and the partition 15 can prevent the material in the sampling chamber 101 from leaking toward the locking assembly 3. During the operation, since the material may generate pressure or flow, the presence of the partition 15 can ensure that the material is confined in the sampling chamber 101 to prevent it from contaminating or damaging the locking assembly 3.

[0077] At the same time, since the drill 2 passes through the partition 15, the partition 15 can also provide certain support for the drill 2, thereby improving the rotation stability of the drill 2 and also improving the safety and accuracy of the operation.

[0078] Specifically, the separator 15 can be set as a circular ring, and the drilling tool 2 can be rotatably supported on the circular ring. In addition, the separator 15 and the first body 11 can be set as an integral structure, and one of them can be a detachable connection structure connected by a snap-fit ​​connection.

[0079] Embodiment 3:

[0080] Reference Figure 2 and Figure 6 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present utility model further have the following technical solutions:

[0081] The handle 1 also includes a first anti-foolproof buckle 13 connected to the first body 11 and a second anti-foolproof buckle 14 connected to the second body 12. The first anti-foolproof buckle 13 and the second anti-foolproof buckle 14 can be rotated forward to engage with each other, and can also be rotated backward to disengage from each other; when the rotary drive member 4 is running, the drilling tool 2 rotates forward.

[0082] The first foolproof buckle 13 and the second foolproof buckle 14 are buckled with each other, so that the two have a unique connection method, avoiding the first body 11 from being incorrectly connected to the second body 12. As for the specific structure of the foolproof buckle, it can be flexibly selected by the staff.

[0083] When the handle 1 needs to be assembled, the user can align the first body 11 with the second body 12, and then rotate the first anti-fool buckle 13 and the second anti-fool buckle 14 in a positive direction to engage with each other. This design can ensure that the handle 1 remains stably connected during surgery and prevent the handle 1 from loosening or separating due to vibration or other factors.

[0084] When the handle 1 needs to be disassembled for cleaning, maintenance or replacement of parts, the user can reversely rotate the first anti-foolproof buckle 13 and the second anti-foolproof buckle 14 to disconnect them. This design makes the disassembly process of the handle 1 simple and fast, and improves the efficiency of the operation.

[0085] When the rotary drive member 4 is in operation, the drill 2 will rotate in the forward direction, and the rotation direction of the drill 2 is exactly the operation direction in which the first body 11 is buckled on the second body 12. Due to the existence of the sleeve 5, the torque transmitted by the drill 2 will inevitably be transmitted to the first body 11, so this excess torque will only strengthen the connection between the first body 11 and the second body 12, and will not cause the first body 11 and the second body 12 to loosen, thereby ensuring the reliability of the connection between the first body 11 and the second body 12, and thus ensuring the reliability of the use of the surgical device.

[0086] Embodiment 4:

[0087] Reference Figure 1 , Figure 3 and Figure 4 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present utility model further have the following technical solutions:

[0088] The human tissue surgical device further comprises a power interface 6 located at the rear end of the second body 12 away from the first body 11 , and the rear end of the second body 12 extends obliquely relative to the axis of the handle 1 ; the power interface 6 is softly wrapped.

[0089] In this embodiment, the surgical device is powered by an external power supply, and the power interface 6 is set to be inclined, which can avoid interference between the power cord and the patient's body during iliac bone sampling. The specific reasons are as follows:

[0090] For some patients with a strong physique, their waist circumference, chest circumference and hip circumference are required. When taking samples from the ilium, the surgical instruments will be almost parallel to the direction of the human body's height. Therefore, the power cord extending along the axial direction of the handle 1 will easily interfere with the human body. After the power interface 6 is set to an inclined form, the power cord can be prevented from colliding with the human body, making it more convenient and flexible for the operating doctor to use.

[0091] The power interface 6 is designed to be wrapped with soft glue, so that the interface is better sealed, the plug is wrapped more tightly, and it is not easy to be pulled out by vertical force when the outlet is bent.

[0092] It can be understood that, except for any conflicting parts, the above-mentioned embodiments 1-4 can be freely combined to form other implementation methods of the present utility model.

[0093] In the description of the present utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0094] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like 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 mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
