Description

Technical Field

[0001] The invention belongs to prostate surgery instruments, and in particular relates to a suspension expansion device used for prostate surgery. Background Art

[0002] Benign prostatic hyperplasia (BPH) is a common disease in middle-aged and elderly men. Its main manifestations include hyperplasia of prostate stroma and glandular components, benign prostatic enlargement (BPE), lower urinary tract symptoms (LUTS), and bladder outlet obstruction (BOO). Currently, there are two treatment methods for BPH: drug therapy and surgical treatment. Surgical treatment includes: (1) transurethral resection of the prostate; (2) suprapubic or retropubic prostatectomy; (3) laser prostatectomy or resection; (4) minimally invasive treatment with implants. Among them, minimally invasive treatment with implants is to implant a permanent implant into the prostate through a delivery system, and use the implant to mechanically separate the two lobes of the prostate so that it no longer blocks the urethra, thereby continuously relieving the symptoms of BPH patients. There is no need to resect or ablate the prostate tissue, which can relieve the pain of patients and enable them to return to normal life as soon as possible.

[0003] Chinese patent 202311679703.7 discloses "a continuously accessible prostate anchor delivery system". The delivery system of the prostate implant usually requires the cooperation of a delivery handle and a delivery pipeline to realize the step-by-step implantation process of the prostate implant, wherein the delivery pipeline includes a main body, a puncture needle system, an anchor wire cutting system, an implant and an imaging system. The puncture needle system is used to pierce the prostate capsule and release the capsule sheet of the implant. The anchor wire cutting system is used to release the urethral end sheet on the prostate urethra side and complete the tightening and cutting of the anchor wire. The specific implantation process of the implant is as follows Figures 30 to 32 As shown in the figure, the delivery handle in this technical solution can cooperate with the puncture needle system and the anchor wire cutting system to realize the full implantation process of the prostate implant. Most of the delivery handles of prostate implants in the prior art have roughly the same operation steps as those in the above patent technology. Their structure is generally a pistol structure, with many internal structural accessories, large overall size and weight, which is inconvenient to operate during prostate surgery.

[0025] To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the following will be combined with the attached Figures 1 to 35 The technical solutions of the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0026] like Figures 30 to 32 As shown, a coronal cross-section of the lower abdomen of a man with prostate hyperplasia, the bladder 01 is a bubble-like structure for storing urine, located behind the human pubic bone 02, and its open end is connected to a soft, elastic tubular structure as the urethra 03, and the urine stored in the bladder is discharged from the front end of the penis through the urethra 03. The prostate 04 is located outside the urethra at the junction of the urethra 03 and the bladder 01. The health of the prostate 04 has an important impact on the normal function of the male reproductive system. For example, if the prostate hyperplasia occurs, it will squeeze the urethra 03 and narrow the urethral passage, which may cause problems such as frequent urination, urgent urination, painful urination, and sexual dysfunction. The prostate capsule 05 is distributed on the outer wall of the prostate 04, and the prostate capsule 05 has a certain structural strength.

[0027] like Fig.29 As shown, the anchor implant is a medical device for minimally invasive surgery to treat prostate hyperplasia, which usually includes a capsule sheet 26 clamped on the outside of the prostate capsule 05, a urethral end sheet 28 clamped on the inner wall of the prostate urethra, and an anchor line 27 connecting the capsule sheet 26 and the urethral end sheet 28. The urethral end sheet 28 is pulled closer to the capsule sheet 26 through the anchor line 27, thereby expanding the urethral stenosis position and clearing the urine discharge passage. The capsule sheet 26 in the prior art adopts a straight structure. After the capsule sheet 26 is released on the outside of the prostate capsule 05, the capsule sheet 26 and the anchor line 27 form a T-shaped structure. When the urethral end sheet 28 is released on the urethra side and fixedly clamped with the anchor line head, an I-shaped structure (such as Fig.29 shown).

[0028] like Figure 1 and Fig.33 As shown, the present invention discloses a suspension expansion device for prostate surgery. The suspension expansion device 100 includes a delivery handle 1 and a delivery pipeline assembly 2.

[0029] like Figures 27 and 28As shown, the delivery pipeline assembly 2 includes a main body 201, a puncture needle assembly, a camera module 206 and a tangent assembly. The radial section of the main body 201 is an elliptical structure. The upper edge, the axis core and the lower edge of the main body 201 are respectively provided with a puncture needle shuttle tube slot 2011, a laparoscope slot 2012 and a tangent shuttle tube slot 2013 along its length direction, and the upper end of the puncture needle shuttle tube slot 2011 and the lower end of the tangent shuttle tube slot 2013 are open structures. The main body 201 can meet the needs of convenient layout of the puncture needle assembly, the camera module and the tangent assembly. The puncture needle assembly includes a puncture needle shuttle tube 202 that is mounted in a puncture needle shuttle tube slot 2011 and a puncture needle push tube 203 that is slidably connected to the puncture needle shuttle tube 202. The front end of the puncture needle push tube 203 is connected to a puncture needle head 205, and a capsule membrane sheet 26 is stored in the puncture needle head 205. The rear end of the capsule membrane sheet 26 is fixedly connected to an anchor line 27. A capsule membrane sheet push tube 204 is provided at the rear end of the capsule membrane sheet 26 in the puncture needle push tube 203, and the anchor line 27 is stored in the capsule membrane sheet push tube 204. The puncture needle head 205 moves forward under the push of the puncture needle push tube 202 to puncture the lateral lobe of the prostate (such as Fig.30 As shown). The puncture needle 205 contains a capsule sheet 26, and during the puncture process of the puncture needle 205, the capsule sheet 26 and the anchoring line 27 are synchronously punctured into the prostate capsule 05. As the puncture needle push tube 203 shrinks backward and drives the puncture needle 205 to retract, the capsule sheet push tube 204 moves forward relative to the puncture needle push tube 203 (the position of the capsule sheet push tube 204 remains unchanged), so that the capsule sheet 26 is released from the outer wall of the prostate capsule 05 and automatically pops open. After the capsule sheet 26 pops open, it forms a T-shaped structure with the anchoring line 27, and then the capsule sheet push tube 204 continues to move backward with the puncture needle push tube 203, pulling the anchoring line 27 backward to tighten the capsule sheet 26 on the outer wall of the prostate capsule 05 (as shown). Fig.31 shown).

[0030] like Figures 27 and 28As shown, the thread cutting assembly includes a thread cutting shuttle tube 207 which is clamped in the thread cutting shuttle tube slot 2013, a thread cutting knife tube 208 is installed in the thread cutting shuttle tube 207, a urethra end piece pushing rod 209 is installed in the thread cutting knife tube 209, and a urethra end piece 28 is arranged at the front end of the urethra end piece pushing rod 209, and the thread cutting shuttle tube 207, the thread cutting knife tube 208 and the urethra end piece pushing rod 209 all adopt a square structure. A thread cutting edge is arranged at the front end of the thread cutting knife tube 208. A V-shaped notch for the anchoring wire 27 to be inserted is provided at the front end of the urethral end piece 28. After the cystic membrane piece 26 is released and the anchoring wire 27 is tightened, the urethral end piece pushing rod 209 pushes the urethral end piece 28 forward. During the advancement of the urethral end piece 28, the anchoring wire 27 is correspondingly connected to the root of the V-shaped notch, thereby realizing the anchoring of the anchoring wire 27 and the urethral end piece 28. Then, the cutting knife tube 208 is pushed backward to move along the cutting shuttle tube 207. During the movement, the cutting edge of the cutting knife tube 208 and the V-shaped notch of the urethral end piece 28 form a scissors difference, so that the anchoring wire 27 can be cut and cut, thereby completing the release of the anchoring implant (such as Fig.32 shown).

[0033] like Figures 2~5As shown, the support frame 8 includes a first support side plate 81 and a second support side plate 82 which are vertically arranged on both sides of the support base plate 701. The first support side plate 81 and the second support side plate 82 form an I-shaped structure with the support base plate 701. A first mounting groove 83 and a second mounting groove 84 are respectively formed on the upper and lower sides of the support base plate 701. The main frame 7 and the support frame 8 form the main frame of the conveying handle 1. The main frame is made of metal material, and its structure has high strength and stability.

[0034] like Figures 6 to 9 and Fig.35 As shown, the puncture needle slider 12 is slidably connected to the rear end of the first installation slot 83, and the puncture needle slider 12 is fixedly connected to the puncture needle push tube 203. An elastic connection component 9 is provided at the front end of the first installation slot 83, and the puncture needle slider 12 is connected to the elastic connection component 9 through the puncture spring 10. Specifically, the puncture needle slider 12 includes a guide slider 121, and guide sliders 127 slidably connected to the first support side plate 81 and the second support side plate 82 are provided on both sides of the guide slider 121. Constant force spring mounting seats 123 for the constant force spring 14 to be clamped are provided on both sides of the rear end of the guide slider 121, that is, the constant force spring 14 includes two correspondingly arranged on the guide slider 121. The top surface of the guide slider 121 is located at the front side of the constant force spring mounting seat 123 and is correspondingly provided with a first limiting wedge 122, and the guide slider 121 is provided with a spring connecting column 124 between the two first limiting wedges 122, and one end of the puncture spring 10 is suspended on the spring connecting column 124. The front end of the guide slide 121 is arranged on the first driving arm 125, and a puncture needle pushing tube block 126 is arranged on the inner side of the front end of the first driving arm 125. The end of the puncture needle pushing tube 203 can be fixedly connected to the puncture needle pushing tube block 126. As the puncture needle slider 12 moves forward or backward along the supporting base plate 701, the puncture needle pushing tube block 126 can push the puncture needle pushing tube 203 forward or backward along the puncture needle shuttle tube 202, thereby promoting the puncture needle 205 to pierce or retract.

[0035] like Figure 4 and Fig.15As shown, the puncture needle lever 11 is arranged on the upper side of the puncture needle slider 12, and the puncture needle lever 11 is clamped on the puncture needle slider 12 and restricts it from sliding forward. Specifically, a first driving rod 1101 is arranged on the front end of the puncture needle lever 11 near the first supporting side plate 81, and the first driving rod 1101 penetrates the first supporting side plate 81. First pivots 1102 rotatably connected to the first supporting side plate 81 and the second supporting side plate 82 are arranged on both sides of the middle part of the puncture needle lever 11, respectively, and the puncture needle lever 11 can perform a small range of rotation through the first pivot 1102. The lower side of the rear end of the puncture needle lever 11 is correspondingly supported on the front side of the first limiting wedge 122, and a first limiting slot 1103 is arranged on the upper side of the rear end of the puncture needle lever 11 along its width direction. A first stopper 13 is provided at the rear end of the puncture needle lever 11 on the inner side of the first support side plate 81. The first stopper 13 is an L-shaped structure, and a clamping column 1301 supported in the first limit slot 1103 is provided at the front end of the first stopper 13. The clamping column 1301 is correspondingly supported in the first limit slot 1103 of the puncture needle lever 11, thereby limiting the rotation of the puncture needle lever 11. When it is necessary to release the position restriction of the puncture needle lever 11 on the puncture needle slider 12, the puncture needle lever 11 can be driven to rotate along the first pivot 1102 by applying a downward force to the first driving rod 1101, and the resistance of the first stopper 13 acting on the rear end of the puncture needle lever 11 is overcome, so that the first stopper 13 is deformed, so that the rear end of the puncture needle lever 11 is separated from the contact with the first limit wedge 122, and the puncture needle slider 12 can slide forward under the action of the puncture spring 10, thereby pushing the puncture needle push tube 203 forward to puncture the needle 205.

[0036] like Figure 4 , Figure 7 and Fig.10The diaphragm sheet slider 18 is fixedly connected to the diaphragm sheet push tube 204. The diaphragm sheet slider 18 is slidably connected in the first mounting groove and is located at the front end of the puncture needle slider 12. The puncture needle slider 12 is elastically connected to the diaphragm sheet slider 18 through the constant force spring 14, and the constant force spring 1 is initially in an untensioned state. Specifically, the diaphragm sheet slider 18 includes a support buckle plate 186 supported on two first guide slides 702. Both sides of the rear end of the support buckle plate 186 are respectively provided with support slide plates 181 slidably supported on the support base plate 701. The position of the support slide plate 181 is lower than the height of the support buckle plate 186. The rear end of the support slide plate 181 is provided with a connecting column 182 for connecting the constant force spring 14. The constant force spring 14 is rotatably connected to the constant force spring mounting seat 123 of the puncture needle slider 12. The constant force spring The free end of 14 is suspended on the connecting column 182. The function of the constant force spring 14 is that when the puncture needle slider 12 slides backward and drives the puncture needle push tube 203 to return backward, the constant force spring 14 can provide a pulling force for the capsule membrane slider 18 to return in sequence, thereby driving the capsule membrane slider push tube 204 to return backward, and the constant force spring 14 can make the puncture needle slider 12 and the capsule membrane slider 18 have an action time difference when returning backward, thereby delaying the capsule membrane slider 18 from sliding backward and returning. The rear end of the support buckle plate 186 is located between the two support slide plates 181 and is provided with a second drive arm 183 that cooperates with the first drive arm 125. The rear end bottom surface of the second drive arm 183 is provided with a capsule film push tube clamp 184. The rear end of the capsule film push tube 204 extends out of the puncture needle push tube 203, so that the capsule film push tube 204 is clamped on the capsule film push tube clamp 184. When the capsule film push tube clamp 184 slides forward or backward along the first installation slide groove 83, it can drive the capsule film push tube 204 forward or backward, thereby realizing the forward release of the capsule film 26 and the backward pulling and tensioning action of the anchor line 27. The first drive arm 125 and the second drive arm 183 are respectively provided with a 1 / 4 concave arc along the length direction to form a semicircular groove structure, so as to facilitate the wiring of the connection cable of the camera module 206. During operation, after the puncture needle lever 11 is driven to release the restriction on the puncture needle slider 12, the puncture needle slider 12 slides forward under the action of the puncture spring 10 to drive the puncture needle 205 forward to puncture the lateral lobe of the prostate. The front end of the first driving arm 125 of the puncture needle slider 12 is supported on the supporting slide 181, thereby pushing the capsule sheet slider 18 to slide forward, and then driving the second driving arm 183 to move forward, pushing the capsule sheet push tube 204 to move forward along with the puncture needle push tube 203, that is, during the puncture process of the puncture needle 205, the capsule sheet 26 stored in the puncture needle 205 passes through the lateral lobe of the prostate, preparing for the release of the capsule sheet 26.

[0037] like Figure 4 , Figure 7 , Fig.10 and Fig.16 As shown, a second limiting wedge 185 is arranged at the front end of the supporting slide plate 181 near the first supporting side plate 81, and the second limiting member 15 is fixedly connected to the inner side of the first supporting side plate 81, and the second limiting member 15 is correspondingly arranged on the upper side of the diaphragm sheet slider 18. The second limiting member 15 is correspondingly arranged on the upper side of the diaphragm sheet slider 18. As the puncture needle stimulates the puncture needle slider 12, the diaphragm sheet slider 18 is driven to move forward synchronously, and the second limiting member 15 is clamped on the diaphragm sheet slider 18 to limit its backward sliding; as the puncture needle is retracted, the puncture needle slider 12 moves backward and the position of the diaphragm sheet slider 18 is limited and locked, so that the constant force spring 14 is tightened and stored. Specifically, the second limit member 15 can adopt a limit buckle structure, including a clamping strip 151, a limit clamping tooth 152 supported on the second limit wedge block 185 is provided at the front end of the clamping strip 151, and a mounting block 154 is provided at the rear end of the clamping strip 151, and the mounting block 154 is correspondingly connected to the inner side of the first support side plate 81; a second driving rod 153 is provided on the front end of the clamping strip 151 close to the first support side plate 81, and the second driving rod 153 passes through the first support side plate 81; it should be noted that the second limit member 15 can also adopt a lever-like structure, which needs to be coordinated with the structure of the rotation drive component 3. When the diaphragm slider 18 is pushed forward into position along with the puncture needle slider 12, under the driving power of the puncture needle slider 12, the second limiting wedge block 185 will move forward and lift the limiting tooth 152 of the second limiting member 15 and move it to the front side of the limiting tooth 152. At this time, the limiting tooth 152 can be clamped on the second limiting wedge block 185 under the action of its reset elastic force, thereby limiting the diaphragm slider 18 from resetting backward; when the puncture needle slider 12 slides backward, the limiting tooth 152 limits the diaphragm slider 18 from moving backward, thereby causing the constant force spring 14 to stretch and store energy. This process corresponds to the puncture needle slider 12 moving forward to the position to complete the puncture needle 205 to complete the puncture. When the puncture needle slider 12 moves backward, the puncture needle push tube 203 drives the puncture needle 205 to retract. The second limiter 15 limits the capsule sheet slider 18 to reset backward, so that the capsule sheet 26 moves forward relative to the puncture needle 205. At this time, the capsule sheet 26 does not move, and the puncture needle 205 retracts backward to release the capsule sheet 26 on the outside of the prostate capsule 05. After the capsule sheet 26 is released, the second driving rod 153 is driven to move slightly upward to drive the limiter tooth 152 to move upward to contact the restriction of the second limiter wedge 185. When the puncture needle slider 12 continues to move backward, the constant force spring 14 can drive the capsule sheet slider 18 to slide backward, and the capsule sheet push tube 204 moves backward to pull the anchor line 27 to tighten the capsule sheet 26 on the outside of the prostate capsule 05.

Specifically, the top surface of the cutting knife slider 19 is provided with a cutting knife tube clamping block 191 that is slidably connected to the limiting groove 703, the rear end of the cutting knife slider 19 is provided with a spring connecting block 192 for connecting the cutting spring 21, and the bottom surface of the cutting knife slider 19 is provided with a clamping strip 193. The top surface of the urethral end piece slider 23 is provided with a urethral end piece push rod clamping block 231 that is slidably connected to the limiting groove 703, and the lower side of the rear end of the urethral end piece slider 23 is provided with a third limiting clamping groove 232.

[0039] like Figure 4 and Fig.18 As shown, the push rod lever 22 is correspondingly arranged at the lower side of the urethral end piece slider 23, and the push rod lever 22 is clamped on the urethral end piece slider 23 and limits its forward sliding. Specifically, a third driving rod 223 is arranged at the front end of the push rod lever 22 near the first supporting side plate 81, and the third driving rod 223 penetrates the first supporting side plate 81; third pivots 222 are respectively arranged on both sides of the middle part of the push rod lever 22, which are rotatably connected to the first supporting side plate 81 and the second supporting side plate 82; a second limiting end 221 is arranged at the rear end of the push rod lever 22, which is clamped in the third limiting slot 232. In a normal state, the push rod lever 22 is correspondingly clamped in the third limiting slot 232 of the urethral end piece slider 23 through the second limiting end 221, thereby limiting the urethral end The sheet slider 23 moves forward to keep the urethral end sheet 28 in the starting state in the cutting knife tube 208; when the capsule sheet pushing tube 204 moves backward to tighten the anchor line 27, the third driving rod 223 is driven to make a small displacement upward, so that the pushing rod lever 22 rotates along the third pivot 222, and the second limit end 221 can be disengaged from the third limit slot 232. The urethral end sheet slider 23 moves forward under the traction of the cutting spring 21, thereby driving the urethral end sheet pushing rod 209 to move forward to push the urethral end sheet 28 out, so that the V-shaped bayonet of the urethral end sheet 28 is engaged with the anchor line.

[0040] like Figure 4 , Figures 11-12 , Fig.17As shown, the cutting blade lever 20 is correspondingly arranged between the cutting blade slider 19 and the urethra end piece slider 23, the front end of the cutting blade lever 20 is correspondingly clamped on the cutting blade slider 19 and restricts its backward sliding, and the rear end of the cutting blade lever 20 can limit the forward sliding position of the urethra end piece slider 23. Specifically, the cutting blade lever 20 is a boat-shaped structure, and the second pivot shaft 2002 rotatably connected to the first supporting side plate 81 and the second supporting side plate 82 is respectively arranged on both sides of the middle part; the second limiting slot 2003 for clamping the clamping strip 193 is arranged on the upper side of the front end of the cutting blade lever 20, and the rear end of the cutting blade lever 20 forms a first limiting end 2001 for driving and limiting the urethra end piece slider 23. Under normal conditions, the cutting knife slider 19 is clamped in the second limiting slot 2003 of the cutting knife lever 20 through the clamping strip 193, so that the cutting knife slider 19 cannot move backward; at this time, there is a distance between the first limiting end 2001 of the cutting knife lever 20 and the urethra end piece slider 23 to meet the requirement of the urethra end piece slider 23 sliding forward. When the push rod lever 22 releases the restriction on the urethral end piece slider 23, the urethral end piece slider 23 slides forward under the action of the cutting spring 21, and the front inclined surface of the urethral end piece slider 23 will be supported on the first limit end 2001 of the cutting knife lever 20 during the movement, giving the first limit end 2001 a force to rotate upward, so that the cutting knife lever 20 rotates through the second pivot 2002, and the second limit slot 2003 is out of contact with the card strip 193, and the cutting knife slider 19 can slide backward close to one side of the urethral end piece slider 23 under the action of the cutting spring 21. During the backward movement of the cutting knife slider 19, it drives the cutting knife tube 208 to move backward and forms a scissors difference with the V-shaped bayonet of the urethral end piece 28 to complete the intermittent action on the anchor line 27. The cooperation of the cutting knife slider 19, the cutting knife lever 20, the pushing rod lever 22 and the urethral end piece slider 23 of this structure can continuously and automatically realize the process of releasing the urethral end piece 28 and cutting the anchor line 27, thereby improving the convenience of operation.

[0041] like Figures 1 to 3 , Figures 19 to 23 and Fig.34As shown, the rotary drive assembly 3 is correspondingly arranged on the outside of the first supporting side plate 81, and the rotary action of the rotary drive assembly 3 can successively drive the puncture needle lever 11, the second limiter 15, the push rod lever 22 and the cutting knife lever 20 to perform corresponding actions, and successively release the restrictions on the puncture needle slider 12, the capsule sheet slider 18, the urethra end sheet slider 23 and the cutting knife slider 19 to complete the implantation of the prostate implant. Specifically, the rotary drive assembly 3 includes a drive housing 4 correspondingly buckled on the outside of the first supporting side plate 81, and a mounting circular groove 401 is arranged in the middle of the drive housing 4, and a driving wheel 5 is arranged in the mounting circular groove 401. The driving wheel 5 includes a disk body 501, and four paddles 502 are distributed along the circumference of the disk surface on the outside of the disk body 501. The paddles 502 are correspondingly provided with digital numbers. The paddles 502 can be used to sequentially to toggle the driving wheel 5 to perform a rotation action to achieve different implantation steps of the prostate implant. A first driving block 503 is arranged on the inner periphery of the disk body 501, and the second driving rod 153 of the second limiting member 15 corresponds to the outer periphery of the supporting disk body 501 and is located in front of the first driving block 503. When the driving wheel 5 rotates to make the first driving block 503 rotate to the second driving rod 153 and lift it up, the second limiting member 15 can contact the restriction on the diaphragm slider 18, so that the diaphragm slider 18 can slide backward under the action of the constant force spring 14 to complete the tensioning process of the anchor line 27. An outer driving ring body 510 and an inner driving ring body 511 are concentrically arranged on the inner disk surface of the disk body 501, and a limiting ring groove 507 for the third driving rod 223 to be clamped is formed between the outer driving ring body 510 and the inner driving ring body 511. A second driving block 508 is arranged on the inner wall of the outer driving ring body 510, and the third driving rod 223 of the pushing rod lever 22 is correspondingly slidably connected in the limiting ring groove 507. When the driving wheel 5 rotates to make the second driving block 508 rotate to the third driving rod 223 and push it upward, the pushing rod lever 22 releases the restriction on the urethral end piece slider 23, and the urethral end piece slider 23 completes the process of pushing the urethral end piece 28 into place and opening the cutting process of the anchor line 27 under the action of the cutting spring 21. The first driving rod 1101 of the puncture needle lever 11 is correspondingly arranged on the inner side of the inner driving ring body 511, and the third driving block 509 is arranged on the inner side of the inner driving ring body 511. When the driving wheel 5 rotates to make the third driving block 509 rotate to the first driving rod 1101 and press it down, the puncture needle lever 11 releases the restriction on the puncture needle slider 12, and the puncture needle slider 12 completes the puncture process of the puncture needle 205 under the action of the puncture spring 10. The driving wheel 5 can be cleverly structured, and different implantation steps of the prostate implant can be realized through its rotation.

[0042] like Figures 4 and 5 and Figures 13 and 14As shown, a first mounting column 812 is arranged on the outer side of the first supporting side plate 81, and a supporting sleeve 505 correspondingly buckled on the first mounting column 812 is arranged at the inner center of the driving wheel 5, that is, the driving wheel 5 is buckled on the outer end of the first mounting column 812 through the supporting sleeve 505. A second mounting column 813 is arranged on the lower side of the first mounting column 812, and a transmission gear 17 is sleeved on the second mounting column 813. The inner wall of the inner driving ring body 511 is provided with an inner tooth area 506 meshing with the transmission gear 17. When the driving wheel 5 rotates so that the inner tooth area 506 meshes with the transmission gear 17, the transmission gear 17 can be driven to rotate to realize power transmission; in the non-meshing state, the transmission gear 17 can rotate freely without power transmission. The transmission gear 17 is meshedly connected with a transmission rack 16 on its upper side, and a guide sliding long hole 1601 is provided in the middle of the transmission rack 16 along its length direction for the first mounting column 812 to pass through, and a transmission tooth area 1602 is provided on the bottom edge of the transmission rack 16 along its length direction; the first supporting side plate 81 is provided with a first guide sliding groove 814 along its length direction, and the guide sliding block 127 of the puncture needle sliding block 12 passes through the first guide sliding groove 814 and is fixedly connected to the transmission rack 16. When the puncture needle slider 12 slides forward along the first mounting slot 83 to realize the puncture needle 205 to perform the puncture action, the guide slider 127 can drive the transmission rack 16 to move forward along the first mounting column 812 during the process of moving forward, and the transmission rack 16 drives the transmission gear 17 to idle during the forward movement, that is, the dynamic transmission rack 16 does not work during the forward movement of the puncture needle slider 12; when it is necessary to drive the puncture needle slider 12 to reset backward to complete the retraction of the puncture needle 205, the driving wheel 5 rotates into place so that the inner tooth area 506 is meshed with the transmission gear 17, and as the driving wheel 5 rotates, the transmission gear 17 rotates and drives the transmission gear 17 to move backward, thereby driving the puncture needle slider 12 to move backward along the first mounting slot 83 to complete the retraction process of the puncture needle 205.

[0043] In a preferred embodiment, if Figure 3 and Figure 22-23 As shown, a ratchet area 504 is provided on the outer periphery of the disk body 501, and a pawl buckle 24 engaged with the ratchet area 504 is provided on the inner side of the driving shell 4. The driving wheel 5 of this arrangement can limit its rotation direction through the pawl buckle 24 to avoid medical accidents caused by operational errors; and this arrangement improves the rotation stability of the driving wheel 5.

[0044] In a preferred embodiment, if Figure 5 and Fig. 20As shown, the first support side plate 81 is provided with a second guide slide bar 811 on the upper side of the first guide slide groove 814, and the inner side of the transmission rack 16 is provided with a second guide slide groove 1603 corresponding to the second guide slide bar 811; the transmission rack 16 provided in this way can stably slide along the first support side plate 81, thereby improving the sliding stability of the puncture needle slider 12. It should be noted that the first support side plate 81 and the second support side plate 82 are also provided with a plurality of mounting holes 815 according to requirements, and the specific positions of the mounting holes are set according to requirements, which will not be described in detail here.

[0045] In a preferred embodiment, if Figure 3 , Fig.19 and Figures 21 and 22 As shown, a locking groove 5031 is provided on the outer side of the first driving block 503, and an unlocking assembly 6 is correspondingly provided at the rear end of the driving housing 4. The unlocking assembly 6 includes an unlocking push block 601 provided on the outer side of the driving housing 4 and an unlocking plug block 602 provided on the inner side of the driving housing 4. The unlocking push block 601 is fixedly connected to the unlocking plug block 602 through a pin shaft; the front end of the unlocking plug block 602 is correspondingly inserted into the locking groove 5031, and the rear end of the unlocking plug block 602 is provided with an unlocking spring 603 provided between the unlocking plug block 602 and the driving housing 4. Under normal conditions, the unlocking plug block 602 is inserted into the locking groove 5031 of the first driving block 503 under the action of the unlocking spring 603, thereby locking the driving wheel 5; when the unlocking push block 601 is pushed backward to drive the unlocking plug block 602 to move backward to overcome the resistance of the unlocking spring 603, the driving wheel 5 can be unlocked, so that the driving wheel 5 can rotate.

[0046] In a preferred embodiment, if Figure 4 and Fig.26 As shown, the elastic connection assembly 9 includes a support column 91 installed between the first support side plate 81 and the second support side plate 82, and a spring buckle 92 and a torsion spring 93 are mounted on the support column 91. The spring buckle 92 is suspended and connected with the puncture spring 10, and the torsion spring 93 is supported on the side wall of the spring buckle 92 and limits the opening direction of the hook. The elastic connection assembly 9 is tensioned and connected with the puncture spring 10 during the puncture needle power accumulation process. After the puncture needle slider 12 is released from the restriction, the puncture spring 10 is excited and relaxed. Since the puncture spring 10 relaxes the traction on the spring buckle 92, the spring buckle 92 rotates at a certain angle under the drive of the torsion spring 93, so that the opening offset of the hook of the spring buckle 92 is disconnected from the spring hook of the puncture spring 10, so that the puncture needle slider 12 can be easily moved to the right along the first installation slide groove 83 to reset during the process of moving backward to drive the puncture needle 205 to retract, thereby greatly reducing the difficulty of retracting the puncture needle 205.

[0047] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
