Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to a lung biopsy device with a rib punching function. Background Art

[0002] As is known, a lung biopsy device is a medical device that can be used for sampling and aspirating cells from lung lesions. Currently, clinically used lung biopsy devices (Bade biopsy guns and Bard biopsy needles) are only suitable for soft tissues and cannot penetrate bones. Therefore, if the lesion is behind the ribs, it is impossible to perform a biopsy through percutaneous lung biopsy, so that the lung biopsy device cannot extract cells from the lung lesions, affecting the biopsy results of the lung lesions. At this time, a lung biopsy device with a rib perforation function is needed to perforate the ribs, and then the lung biopsy device can be used to extract the lesion cells behind the ribs through the rib perforation, so that the lesions behind the ribs can be biopsied.

[0003] For example, the patent with the publication number CN211883944U and the publication date of November 10, 2020, entitled "A Positioning and Punching Device for Orthopedic Treatment", discloses a positioning and punching device for orthopedic treatment, including a support mechanism, and a fixing mechanism installed above the support mechanism for supporting and installing a fixed drilling device, characterized in that it also includes a control mechanism for controlling whether the drilling device is running and displaying its descent height, and a drilling feed mechanism installed on the fixing mechanism for drilling and realizing up and down lifting movements, wherein the control mechanism and the support mechanism are both connected to the fixing mechanism. The patent can detect the descent height of the drill bit through the control mechanism, thereby facilitating the operator to control the drilling feed mechanism to control the drilling depth, and the distance between the movable legs can be changed through the support mechanism, thereby increasing the practicality and scope of application of the device, and the device is easy and simple to operate, small in size, and convenient to carry and move.

[0004] The deficiency of the prior art is that when taking biopsy samples of the lesion cells behind the ribs, the ribs need to be punched. The prior art first uses a drilling device to drill the ribs, and then takes them out after drilling through the ribs. Then, a lung biopsy is used to take samples of the lesion cells. When the drilling device drills the ribs, bone chips are present in the bone perforations on the ribs. When the lung biopsy needle is inserted from the bone perforations into the lesion location, the lung biopsy needle will collect some bone chips, thereby affecting the purity of the lesion cells extracted by the lung biopsy needle, and further affecting the detection results of the lesion cells.

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, Figure 1 To Attachment Fig.12 The present invention is further described in detail.

[0033] An embodiment provided by the present invention relates to a lung biopsy device with a rib perforation function, including a biopsy needle body, the biopsy needle body including a shell 1, a biopsy needle 2 is arranged on the shell 1, and also includes a drilling mechanism, the drilling mechanism includes a shell 3 and a drill body 4, the drill body 4 is rotatably arranged on the shell 3, a through groove 5 is provided in the drill body 4 along its axial direction, and the biopsy needle 2 passes through the through groove 5 to achieve biopsy of lesion cells by the biopsy needle 2.

[0034] Specifically, the lung biopsy equipment is a medical device for sampling live tissue and aspirating cells from lung lesions. The rib punching function is a device that can drill holes in the ribs. The biopsy needle body is a medical device composed of a shell 1, a biopsy needle 2, a movable rod and a sample collector. The shell 1 is a protective sleeve for wrapping the biopsy needle 2 and the sample collector; the biopsy needle 2 is a hollow tube that can be inserted into the tissue to be sampled for sampling; the movable rod is a device for controlling the movement of the biopsy needle 2, which can make the biopsy needle 2 move. The biopsy needle 2 moves in the tissue and collects samples; the sample collector is a container for collecting tissue samples. This is the structure and function of the biopsy needle body, which is common knowledge in the art and will not be repeated. The drilling mechanism includes a shell 3 and a drill body 4. One end of the drill body 4 is rotatably arranged in the shell 3. The top of the shell 3 is provided with a hole connected to the through groove 5 on the drill body 4. The drill body 4 is provided with the through groove 5 along its axis. The through groove 5 is slightly larger than the biopsy needle 2, so that the biopsy needle 2 can pass through the through groove 5.The drilling mechanism also includes a driven gear 7. A driven gear 7 is arranged on the top outer wall of the drill body 4 located in the shell 3. A driving member 6 is arranged on the top inner wall of the shell 3. The output end of the driving member 6 is connected to a driving gear 8. The driving gear 8 and the driven gear 7 are meshed with each other. When it is necessary to drill holes in the ribs, the medical staff holds the shell 3 and aligns the drill body 4 with the position on the ribs where holes need to be drilled (that is, the position of the lesion behind the ribs). It is known to those skilled in the art that the shell 3 can be installed on a linear motion mechanism capable of distance measurement (a mechanism capable of linear reciprocating linear motion, and the distance of the linear motion can be monitored and measured. The bone opening mechanisms in existing surgeries all have corresponding technologies, both manual and automatic bone drilling mechanisms), so that the linear motion mechanism can drive the shell 3 and the drill body 4 to move, so that the drill body 4 can perform precise drilling operations on the ribs, so that the drilling depth on the ribs can be controlled, and the driving member 6 is started (the driving member 6 is a device that provides a rotational driving force for the driving gear 8 , preferably a motor) drives the driving gear 8 to rotate. Due to the mutual meshing between the driving gear 8 and the driven gear 7, the driving gear 8 drives the driven gear 7 to rotate, and the driven gear 7 drives the drill body 4 to rotate, so that the drill body 4 drills the rib. With the assistance of the ultrasonic device, the drill body 4 drills the rib until the drill body 4 drills through the rib. The drill body 4 stays at the connection part between the rib and the rear tissue cells. At this time, bone perforation occurs on the rib, so that the drill body 4 will The ribs are drilled without damaging the cells and tissues behind the ribs. Then the medical staff passes the biopsy needle body through the through slot 5, so that the biopsy needle body extracts the lesion cells and tissues behind the ribs. It is common knowledge in the art that the biopsy needle body extracts the cells and tissues behind the ribs. It will not be repeated. The biopsy needle body passes through the through slot 5 and extends into the cells and tissues, so that the bone scraps generated when the drill bit body 4 drills the ribs will not affect the extraction of cells and tissues by the biopsy needle body, thereby improving the accuracy of the lung lesion cell biopsy results. ;

[0035] The deficiency of the prior art is that when taking biopsy samples of the lesion cells behind the ribs, the ribs need to be punched. The prior art first uses a drilling device to drill the ribs, and then takes them out after drilling through the ribs. Then, a lung biopsy is used to take samples of the lesion cells. When the drilling device drills the ribs, bone chips are present in the bone perforations on the ribs. When the lung biopsy needle is inserted from the bone perforations into the lesion location, the lung biopsy needle will collect some bone chips, thereby affecting the purity of the lesion cells extracted by the lung biopsy needle, and further affecting the detection results of the lesion cells.

[0036] The beneficial effect of this embodiment is that when it is necessary to perform a biopsy on the lung lesion cells behind the ribs, the medical staff drills the ribs through the drill bit body 4 on the drilling mechanism. With the assistance of the ultrasonic device, the drill bit body 4 can drill through the ribs without damaging the cells and tissues behind the ribs. Then the medical staff uses the biopsy needle 2 on the biopsy needle body to pass through the through groove 5 on the drill bit body 4 until the biopsy needle 2 takes out the lung lesion cells behind the ribs. The bone chips generated when the drill bit body 4 drills the ribs will not affect the extraction of lung lesion cells by the biopsy needle 2, thereby improving the accuracy of the lung lesion cell biopsy results.

[0037] In another embodiment provided by the present invention, refer to Figure 6 and Fig.10 A chip removal groove 9 is provided on the outer wall of the middle and lower part of the drill body 4, and a positioning cylinder 10 is rotatably connected to the top of the chip removal groove 9; the positioning cylinder 10 is sleeved on the outer wall of the drill body 4, and the positioning cylinder 10 and the outer wall of the drill body 4 are rotatably sealed and connected, and the bottom end of the positioning cylinder 10 is rotatably sealed and connected to the top of the chip removal groove 9, and a through groove 12 is provided on one side wall of the chip removal groove 9, that is, the drill body 4 is a two-layer composite structure, and a chip removal groove 9 is provided on the drill body 4. The inner wall of the chip removal groove 9 and the connecting part of the positioning cylinder 10 and the drill body 4 are connected to each other to form a chip removal channel, the inner wall of the chip removal groove 9, the positioning cylinder 10 is rotatably sealed and connected to the top of the drill body 4, and the outer wall of the positioning cylinder 10 and the bottom radius of the drill body 4 are the same.

[0038] Specifically, when the drill body 4 is drilling holes in the ribs, the drill body 4 drives the spiral plate 11 to rotate. Since the positioning cylinder 10 and the outer wall of the drill body 4 are rotationally sealed and connected, the positioning cylinder 10 will not rotate when the drill body 4 rotates. Bone chips will be generated when the drill body 4 is drilling holes in the ribs. Since a through groove 12 is provided on the side wall of the chip removal groove 9, the bone chips generated by the drill body 4 during drilling enter the chip removal groove 9 from the through groove 12, so that the chip removal groove 9 can collect and process the bone chips, so that the bone chips will not remain in the bone perforations on the ribs, and the bone chips will not fall from the bone perforations into the cells and tissues, thereby improving the accuracy of the lung lesion cell biopsy results.

[0039] In another embodiment provided by the present invention, a spreading unit is provided at the end of the drill body 4, and the spreading unit includes a fan-shaped tip 13. A plurality of grooves 14 are evenly provided at the end of the drill body 4 along its circumferential direction, and a positioning shaft 15 is provided in each of the grooves 14. A fan-shaped tip 13 is rotatably provided on each of the positioning shafts 15, and each of the fan-shaped tips 13 is combined into a conical tip for drilling a hole; a propulsion groove 16 is provided at the bottom end of the drill body 4, and the A square push rod 17 is slidably arranged in the push groove 16, and a chip removal channel interconnected with the through groove 5 is arranged on the square push rod 17. The square push rod 17 and the inner wall of the push groove 16 are connected by a plurality of first elastic members 18 uniformly arranged along the circumferential direction thereof; a plurality of square grooves 19 are uniformly opened on the square push rod 17 along the circumferential direction thereof, and a push round rod 20 is arranged in each of the square grooves 19, and a driven round rod 21 is arranged on each of the sector tip 13, and each of the driven round rods 21 The square push rod 17 is connected to the corresponding pushing round rod 20 by a straight rod 22, and the top of the square push rod 17 is evenly provided with a plurality of locking mechanisms; each of the locking mechanisms is used for the positioning operation of the square push rod 17, so that the first elastic member 18 is in an energy storage state; the locking mechanism includes an insertion rod 23, and the top of the square push rod 17 is evenly provided with a plurality of insertion rods 23, and the top inner wall of the pushing groove 16 is evenly provided with a plurality of slots 24, each of which is slidably provided with a square frame 25, and each of the square frames 25 is provided with an unlocking rod 27, and each of the square frames 25 and the inner wall of the slot 24 are connected by a second elastic member 26, and each of the unlocking rods 27 penetrates the drill body 4 and extends into the through groove 5. Under the elastic action of the first elastic member 18, each of the insertion rods 23 and the corresponding square frame 25 abut against each other, so that the square frame 25 and the insertion rod 23 position the square push rod 17, so that the first elastic member 18 is in an energy storage state.

[0040] Specifically, when the drill body 4 is drilling a hole in the rib, the bone perforation is about to penetrate under the high-speed rotation of the drill bit. Since the front end of the drill body 4 is a sharp conical structure, the sharp conical structure at the end of the drill body 4 will enter the tissue behind the rib, which may cause certain damage to the tissue behind the rib. The end of the top of each of the insertion rods 23 away from the through groove 5 is a first wedge-shaped surface, and the end of the bottom of each of the square frames 25 away from the through groove 5 is a second wedge-shaped surface. The first wedge surface and the second wedge surface are wedge-shaped with each other, and the abutting portion between the insertion rod 23 and the square frame 25 is a concave surface, so that the insertion rod 23 and the square frame 25 can be tightly positioned. Before the drill body 4 drills a hole in the rib, each fan-shaped tip 13 (the number of fan-shaped tips 13) The square push rod 17 drives the insertion rod 23 to move toward one end of the slot 24. Since the first wedge-shaped surface on the insertion rod 23 and the second wedge-shaped surface on the square frame 25 cooperate with each other in a wedge shape, the insertion rod 23 pushes the square frame 25 to move away from the through slot 5. At this time, the square frame 25 squeezes the second elastic member 26 (the second elastic member 26 is a component that can be retracted and reset, preferably a spring), so that the second elastic member 26 is in a compressed state until the top of the insertion rod 23 is in contact with the top of the slot 24. The concave surface of the insertion rod 23 and the square frame 25 are pressed against each other, so that the square frame 25 positions the insertion rod 23. At the same time, the square push rod 17 stretches the first elastic member 18 (the first elastic member 18 is a component that can be retracted and reset, preferably a spring), so that the first elastic member 18 is in a stretched energy storage state. Due to the tight positioning operation of the insertion rod 23 and the square frame 25, the first elastic member 18 is always in a stretched state. When the drill body 4 drills the rib, the drill body 4 drills the rib through the conical tip rib composed of the fan-shaped tips 13. With the assistance of the ultrasonic device, until the drill body 4 and the conical tip composed of the fan-shaped tips 13 enter the hole that is about to penetrate the bone, the drill body 4 stops rotating, and the medical staff inserts the biopsy needle body and the biopsy needle 2 into the through slot 5. When the end of the biopsy needle 2 and the unlocking rod 27 abut against each other, the biopsy needle 2 is inserted into the gap between the unlocking rods 27, and the biopsy needle 2 continues to move into the through slot 5. The biopsy needle 2 pushes each unlocking rod 27 to slide toward one end inside the slot 24. Each unlocking rod 27 pushes the square frame 25 connected thereto to slide into the slot 24. The square frame 25 squeezes the second elastic member 26, so that the second elastic member 26 is in a compressed state, so that the square frame 25 and the insertion rod 23 are separated from each other, so that the insertion rod 23 loses the limit of the square frame 25. Since the first elastic member 18 is in a stretched energy storage state, after the insertion rod 23 loses the limit of the square frame 25,The first elastic member 18 pushes the square push rod 17 to slide toward the outer end of the push groove 16, and the square push rod 17 drives the straight rod 22 to slide toward the outer end of the push groove 16 through the push rod 20. The straight rod 22 pushes the fan-shaped tip 13 to rotate around the positioning shaft 15 through the driven round rod 21, so that the fan-shaped tip 13 opens the end of the bone perforation (for example, Fig.10 and Fig.12 As shown in the figure, each fan-shaped tip 13 is in a dispersed state, so that the fan-shaped tip 13 opens the bone perforation without extending the sharp conical structure of the drill body 4 into the tissue or cells behind the ribs, thereby reducing the damage to the tissue or cells behind the ribs and improving the biopsy effect of the cells or tissues behind the ribs.

[0041] After the biopsy needle body and the biopsy needle 2 have extracted cells or tissues behind the ribs, the medical staff takes out the biopsy needle body and the biopsy needle 2. When the end of the biopsy needle 2 and the unlocking rod 27 are separated from each other, under the rebound action of the second elastic member 26, the second elastic member 26 pushes the square frame 25 to slide toward one end of the through groove 5, and the square frame 25 pushes the unlocking rod 27 into the through groove 5, so that the biopsy needle 2 and the unlocking rod 27 can abut against each other next time. Then the medical staff takes out the drill body 4 from the bone perforation and disinfects the drilling mechanism for the next use.

[0042] In another embodiment provided by the present invention, an adsorption mechanism is provided in the shell 3, and the adsorption mechanism includes a suction pipe 28. A plurality of slide grooves 29 are evenly provided at the bottom end of the drill body 4, and a suction pipe 28 is slidably provided in each of the slide grooves 29. An annular circular groove 30 is provided at the top of each of the slide grooves 29. A plurality of telescopic tubes 31 are evenly connected to the annular circular groove 30 along its circumferential direction. Each of the telescopic tubes 31 is connected to its corresponding suction pipe 28. The side wall of the square push rod 17 and the corresponding suction pipe 28 are connected by a connecting piece 32. Each of the suction pipes 28 and The annular groove 30 is used in cooperation with the corresponding sector tip 13. A dust suction channel 33 is provided at the top of the annular groove 30. A first semi-annular tube 34 is connected to the top of the dust suction channel 33. A second semi-annular tube 35 is rotatably sealed on the outer wall of the first semi-annular tube 34. The first semi-annular tube 34 and the second semi-annular tube 35 are combined into an annular tube body. An adsorption device 36 is provided on the inner wall of the shell 3. A U-shaped tube body 37 is connected to the output end of the adsorption device 36. One end of the U-shaped tube body 37 is connected to the positioning cylinder 10, and the other end of the U-shaped tube body 37 is connected to the second semi-annular tube 35.

[0043] Specifically, the adsorption device 36 is a device that can provide suction (such as an air pump fan, etc.). When the drill body 4 performs a drilling operation on the rib, the drill body 4 drives the first semi-annular tube 34 to rotate. Since the first semi-annular tube 34 and the second semi-annular tube 35 are combined into an annular tube body, and the first semi-annular tube 34 and the second semi-annular tube 35 are rotatably sealed and connected to each other, the second semi-annular plate will not rotate. The second semi-annular plate is connected to the adsorption device 36 through the U-shaped tube body 37. When the medical staff inserts the biopsy needle body and the biopsy needle 2 into the through groove 5, the biopsy needle 2 The end of the square push rod 17 abuts against the unlocking rod 27, the biopsy needle 2 pushes each unlocking rod 27 to release the limit of the square frame 25, the first elastic member 18 pushes the square push rod 17 to slide toward the outer end of the push groove 16, and the square push rod 17 drives the suction tube 28 to move toward the end close to the fan tip 13 through the connecting member 32. The suction tube 28 stretches the telescopic tube 31 (the telescopic tube 31 is a tube body with a length that can be telescopic, such as a telescopic hose, etc.), so that the telescopic tube 31 is in a stretched state. At the same time, each fan tip 13 is dispersed, and each fan tip 13 is in In the dispersed state, at the same time, the suction pipe 28 is pressed against the outer wall of the fan tip 13, and the adsorption device 36 is started at this time, and the adsorption device 36 generates suction, so that the bone chips or broken bones on the fan tip 13 are sucked into the annular groove 30 through the suction pipe 28 and the telescopic pipe 31, and the bone chips or broken bones in the annular groove 30 enter the U-shaped tube body 37 through the dust suction channel 33 and the first half ring tube 34 and the second half ring tube 35 to form an annular tube body, and then the bone chips or broken bones enter the adsorption device 36 from the U-shaped tube body 37, that is, the bone chips or broken bones enter the adsorption device 36. 6 is: suction tube 28-telescopic tube 31-annular groove 30-dust suction channel 33-first semi-annular tube 34 and second semi-annular tube 35 are combined into annular tube body-U-shaped tube body 37-adsorption device 36, which can absorb bone chips or broken bones in bone perforation. At the same time, adsorption device 36 synchronously absorbs bone chips in positioning cylinder 10 and chip removal groove 9 through U-shaped tube body 37, and can comprehensively absorb bone chips or broken bones generated during rib drilling, thereby improving the efficiency of cell or tissue biopsy behind the rib and the accuracy of detection.
