Description

Technical Field

[0001] The invention belongs to the technical field of a left-side displacement surgical repositioning device for a bovine abomasum, and in particular relates to a left-side displacement surgical repositioning device for a bovine abomasum with an external endoscope. Background Art

[0002] When the abomasum of a dairy cow is displaced to the left, the initial symptoms are depression, decreased appetite, less rumination, weakened rumen peristaltic sounds, reduced feces output, diarrhea or alternating dry and thin feces, and basically normal body temperature and breathing; as the disease progresses, left-sided abdominal distension, fluid accumulation, subsidence of the sac, loss of appetite, cessation of rumination, and absence of rumen peristaltic sounds will occur.

[0003] At present, surgical treatment is usually used to treat left-sided displacement of the abomasum. The difference in surgical methods mainly lies in the different incisions used to open the surgical access, which mainly include right incision beside the midline of the abdomen, right flank incision, double incisions of the left and right flanks, and left flank incision with greater omentum fixation. The right incision beside the midline of the abdomen has a very good surgical field of view, is easy to peel off when adhesion occurs, and is easy to fix and restore. When suturing, tension-relieving sutures are required to counteract the greater tension of abdominal pressure. The incision on the right flank is suitable for small dairy cows. When the abomasum adheres to tissues and organs, the operation is more difficult. The incisions on the left and right flanks need to be completed together by the attending physician and the doctor. The restoration process is simple and easy, but this method causes greater trauma to the cow, affecting postoperative recovery. The left flank incision allows direct observation of the abomasum that has moved to the left side, which is particularly suitable for cattle with concurrent forestomach diseases such as rumen indigestion. The left flank incision is suitable for omental fixation, which is also the method currently used by most veterinarians. The standard for the treatment of left flank incision with omental fixation is the existing technology, and the specific operations include preoperative preparation, surgical process, and postoperative care.

[0004] After searching, the patent with publication number CN108158691B discloses a bovine abomasum left displacement surgical reducer with an external endoscope, including a high-pressure gas source, a suture, a reduction needle and a propulsion device. The propulsion device is externally provided with a portable endoscope, and the outer edge of the propulsion device is smooth. The propulsion device includes a propulsion unit, an air supply unit located at the tail of the propulsion unit and connected to the propulsion unit, and a needle storage bin capable of accommodating the reduction needle. The air supply unit includes an air delivery pipe and a connector. The head of the needle storage bin is provided with a needle outlet hole for the reduction needle to pass through. The needle storage bin is provided with a lead wire groove at the needle outlet hole. The propulsion unit includes a main cylinder, an air cylinder, a piston, a piston rod and a buffer pad. The tail of the air cylinder is located outside the main cylinder and connected to the connector of the air supply unit. The piston rod passes through a guide tube provided at the bottom of the main cylinder and enters the needle storage bin. The tail of the reduction needle is fixed to the head of the piston rod. The air delivery pipe is connected to the high-pressure air source, and the air delivery pipe can be flexibly bent to reduce the pressure on the internal organs and reduce the operation time.

[0005] Patent publication number CN109875716B discloses a surgical repositioning device for bovine abomasum left displacement. In this invention, the repositioning needle can be reused in one operation. One repositioning needle can carry three strands of suture thread to find a suitable target position in the right abdomen of the cow, reducing the number of times the repositioning device is withdrawn from the cow's abdominal cavity, thereby reducing the probability of damage to the cow's internal organs and saving operation time, thereby improving the survival rate of the cow.

[0006] In the above two technical solutions, the cow's true stomach left displacement surgical reducer uses a single reduction needle to pierce the cow's abdomen, so as to push the suture out of the body. During the operation, the suture needs to be tied to the reduction needle. Since the suture is relatively thin, it is extremely time-consuming and labor-intensive to untie the suture knot on the reduction needle, and it is also troublesome to pull the suture. At the same time, when the same reduction needle is used to pierce the cow's abdomen, the reduction needle repeatedly reciprocates inside and outside the reducer, which will introduce body fluids or blood in the cow's abdomen into the reducer and cause instrument contamination.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention cooperates with the cylinder, the needle storage mechanism and the driving mechanism. Each time the reset needle is ejected and reset, the direction adjustment column can complete a rotation adjustment, thereby driving multiple storage tubes to achieve switching, conveniently switching the stored reset needle for piercing and leading out operation, preventing the reset needle from being stuck in the cow's abdomen, and conveniently and easily pulling the suture. There is no need to remove and separate the reset needle and the suture, reducing the difficulty of untying the buckle; at the same time, there is no need to pull the reset needle back and forth to pierce the cow's abdomen, preventing the interior of the present invention from being contaminated by the body fluid or blood in the cow's abdomen;

[0024] 2. The present invention cooperates with the pushing member, the driving mechanism, the wire collection assembly and the positioning assembly. When the T-shaped ejector pushes out the reset needles in the storage tube, the reset needles drive the sutures to be led out from the protective shell, and the sutures on the wire collection wheel are directed out from the guide opening of the guide frame. When the direction adjustment column switches the reset needles, the wire collection wheel rotates synchronously with the rotating disk, and the positioning channel avoids the wire collection wheel, thereby preventing the sutures from being scattered and entangled when being led out, ensuring that the sutures are easily pulled out of the cow's belly.

[0025] 3. The present invention cooperates with the needle storage mechanism and the limiting mechanism. When the sterilized reset needle is inserted into the storage tube, the tension spring will pull the card plate to be connected to the annular recess at the tail of the reset needle, thereby ensuring that the reset needle is limited and stuck in the storage tube, preventing the reset needle from shaking in the protective shell, and preventing the reset needle from escaping from the storage tube from the through hole of the rotating disk, which is convenient for limiting the storage of multiple reset needles.

The surface of the disk 402 is extended and penetrated, and a reset needle 405 is inserted into the inner cavity of the storage tube 404. A suture 406 is tied in the front reserved hole of the reset needle 405. At least three storage tubes 404 are provided, so that the storage tube 404 can store at least three reset needles 405. The front reserved hole on the reset needle 405 extends out of the storage tube 404, ensuring that at least three reset needles 405 can be used for the reset operation of the bovine abomasum to prevent the bovine abomasum from twisting. A silicone plug 107 is fixed at the center of the end of the protective shell 1 away from the tail cover 101. A partition slit is opened in the middle of the silicone plug 107 for leading out the reset needle 405. The silicone plug 107 has a partition slit in the middle, so that the reset needle 405 can be led out from the partition slit, and when the reset needle 405 is separated from the silicone plug 107, it is convenient for it to automatically reset, so that the internal components of the protective shell 1 can be isolated from the contact with the bovine abdomen;

[0049] A driving mechanism 5 for controlling the ejection of the reset needle 405 is arranged on one side of the support 3 close to the cylinder 2, and the driving mechanism 5 includes a guide frame 501 fixed to the output rod of the cylinder 2, a slide bar frame 7 slidably docked with the guide frame 501 is fixed to the inner wall of the protective shell 1, a T-shaped ejector rod 502 for pushing the reset needle 405 to move is slidably connected inside the guide frame 501, a protrusion 503 is fixed to one end of the guide frame 501 away from the slide bar frame 7, a direction adjustment column 504 for driving the intermittent deflection of the needle storage mechanism 4 is connected to one side of the cylinder 2 through a bearing seat, and the direction adjustment column 504 is movably docked with the protrusion 503, and a docking block 505 is fixed to one end of the direction adjustment column 504 away from the cylinder 2, and the docking block 505 is docked with the reserved rotating hole in the center of the rotating disk 402;

[0050] A positioning assembly 8 is provided on one side of the support 3 close to the driving mechanism 5. The positioning assembly 8 includes a positioning channel 801 for preventing the T-shaped push rod 502 from sliding. The T-shaped push rod 502 can be supported by the positioning channel 801 to ensure that the T-shaped push rod 502 can move smoothly when pushing the reset pin 405.

[0051] A throttle valve 104 for controlling the gas flow rate is installed on the control handle 103. An endoscope handset 105 is also arranged on the surface of the control handle 103. The optical guide insertion part of the endoscope handset 105 passes through the tail cover 101 and is inserted into the protective shell 1. An endoscope probe 106 is fixed to the front end of the optical guide insertion part of the endoscope handset 105, and the endoscope probe 106 is fixed to the surface of the protective shell 1 close to the silicone plug 107. A threading hole 108 for leading out the suture thread 406 is opened on the surface of the tail cover 101.

[0052] During the specific implementation, the sterilized suture 406 is tied with the reserved hole at the front end of the reset needle 405, and the sterilized reset needles 405 are inserted into the storage tube 404. At the same time, the needle storage bin 401 is positioned and installed on one side of the rotating disk 402 by screws, and then the support 3 is positioned and installed on the inner wall of the protective shell 1. At the same time, the docking block 505 at the front end of the adjustment column 504 is docked with the reserved rotating hole in the center of the rotating disk 402, and then the cylinder 2 is inserted into the tail cover 101, and at the same time, it is ensured that the guide frame 501 on the output rod of the cylinder 2 is slidably docked with the slide rod frame 7. Finally, the tail cover 101 is rotated and screwed with the protective shell 1 to ensure that the present invention is assembled before being inserted into the cow's abdomen for surgery;

[0053] The position of the right abdomen of the cow where the reset needle 405 is to be inserted is shaved, cleaned and disinfected, and the protective shell 1 loaded with the reset needle 405 is pushed into the abdomen of the cow and passed under the rumen of the cow. The head of the protective shell 1 is pressed against the right abdomen of the cow. The position can be confirmed by pressing outwards. At this time, the head of the protective shell 1 can be pushed to the correct position by guidance;

[0054] When the protective shell 1 is aligned to the correct position, the gas source is turned on, and the intake valve on the cylinder 2 is controlled to open while the exhaust valve is closed. The gas is pumped into the cylinder 2 along the gas pipe 102 through the control handle 103, so that the high-pressure gas pushes the guide frame 501 forward along the slide rod frame 7 through the output rod in the cylinder 2, and the guide frame 501 pushes the T-shaped push rod 502 out of the positioning channel 801. When the front end of the T-shaped push rod 502 is guided out of the positioning channel 801, it will pass through the through hole 403 on the surface of the rotating disk 402 and enter the receiving The reset needle 405 is pushed in the receiving tube 404, so that the reset needle 405 passes through the needle outlet of the needle storage bin 401 and the silicone plug 107 on the surface of the protective shell 1, and the reset needle 405 drives the tied and knotted suture 406 to pierce the cow's abdomen. At this time, the reset needle 405 is pulled out and the suture 406 is driven out of the cow's abdomen, ensuring that the suture 406 led out at the same time as the reset needle 405 is easily pulled, and there is no need to remove and separate the reset needle 405 and the suture 406, thereby reducing the difficulty of untying the fastened buckle.

[0055] See also Figure 4A limit ring 407 is provided on the inner wall of the needle storage bin 401 near the needle outlet. The limit ring 407 is made of sponge material and can be used to temporarily store alcohol disinfectant to disinfect the front end needle of the reset needle 405. An annular track for limiting the front end needle of the reset needle 405 is provided inside the limit ring 407. A receiving port flush with the needle outlet is provided on the surface of the limit ring 407. When the reset needle 405 rotates with the rotating disk 402, the reset needle 405 rotates in a circle in the limit ring 407 inside the needle storage bin 401, so that the needle end is protected from deviation by the annular track of the limit ring 407, and when the needle of the reset needle 405 rotates and stops at the receiving port of the limit ring 407, the reset needle 405 is pushed out of the protective shell 1 by the T-shaped ejector rod 502.

[0056] See also Figure 10-Figure 15 The circumferential side surface of the steering column 504 is provided with a slide groove 504a and a reversing slideway 504b, and at least three groups of the slide groove 504a and the reversing slideway 504b are provided. The reversing slideway 504b is connected between the two slide grooves 504a, and the reversing slideway 504b is spirally arranged on the circumferential side of the steering column 504, and the number of the receiving tube 404 and the slide groove 504a is the same;

[0057] The two ends of the reversing slide 504b near the two slide grooves 504a are respectively set as the reset corner end and the starting corner end. The reversing column 504 is provided with a rotation groove 504c near the reset corner end of the reversing slide 504b. The middle of the rotation groove 504c is rotatably connected with a baffle 1 504d.

[0058] A groove 504e close to the slide groove 504a is provided at the starting corner end of the adjustment column 504 near the reversing slide 504b. By providing the groove 504e, it is ensured that when the baffle plate 2 504f is received inside the groove 504e, it will not affect the linear sliding of the protrusion 503 in the slide groove 504a. The internal rotation of the groove 504e is connected with the baffle plate 2 504f. Spring sheets for elastic reset are provided between the baffle plate 1 504d on the inner wall of the rotating groove 504c and between the groove 504e and the baffle plate 2 504f, ensuring that the spring sheets can be used for the elastic reset of the baffle plate 1 504d and the baffle plate 2 504f respectively.

[0059] In specific implementation, when the cylinder 2 drives the T-shaped push rod 502 of the driving mechanism 5 to push out the reset pin 405 inside the storage tube 404, the protrusion 503 at one end of the guide frame 501 will slide in a positive straight line along the slide groove 504a on the surface of the adjustment column 504, and when passing through the starting corner end and the reset corner end of the reversing slide 504b, the starting corner end of the reversing slide 504b will block the protrusion 503 through the baffle 2 504f to ensure that the protrusion 503 slides straightly. When the projection 503 passes the reset corner end, the projection 503 will squeeze the baffle 1 504d at the reset corner end, so that the baffle 1 504d rotates in the rotating groove 504c, so that the baffle 1 504d blocks the reset corner end opening of the reversing slide 504b, so that the projection 503 at one end of the guide frame 501 can move in a straight line from the end close to the cylinder 2 to the end close to the rotating disk 402 in the slide groove 504a of the steering column 504;

[0060] When the reset pin 405 is pulled out of the cow's belly, the air intake valve is closed and the exhaust valve is opened by controlling the air cylinder 2, so that the air cylinder 2 shortens and resets, thereby causing the air cylinder 2 to drive the T-shaped push rod 502 to pass through the storage tube 404 and shrink into the positioning channel 801. At this time, the protrusion 503 at one end of the guide frame 501 will slide reversely in the slide groove 504a to the reset corner end of the reversing slide 504b. When the guide frame 501 pulls the protrusion 503 to continue to reset, the protrusion 503 will be squeezed with the baffle 1 504d in the rotating groove 504c, so that the inclined baffle 1 504d can guide the protrusion 503 to enter the reversing slide 504b. During the resetting process of the guide frame 501, the protrusion 503 will move along the reset corner end of the reversing slide 504b to the starting corner end and squeeze the baffle 2 504f to rotate to The protrusion 503 will then separate from the starting corner end and enter the starting end of the next slide groove 504a. At this time, the protrusion 503 passes through a reversing slide 504b and drives the steering column 504 to complete a deflection of a predetermined angle, so that the rotating disk 402 and the storage tube 404 for temporarily storing the reset needle 405 can be synchronously rotated and adjusted with the steering column 504, ensuring that the rotating disk 402 can drive the multiple storage tubes 404 on the surface to switch when the deflection angle is intermittently rotated, so as to facilitate the piercing operation of the reset needle 405 at another position on the right side of the cow's abdomen. After performing this process for multiple times, all the reset needles 405 can drive the suture 406 to be led out from the right side of the cow's abdomen, ensuring that all the reset needles 405 can be led out of the cow's body to prevent the reset needles 405 from being stuck in the cow's abdomen.

[0061] Then, the reducer is taken out from the left side of the cow's abdomen, the sutures 406 are sutured with the omentum of the cow's abomasum, and all the sutures 406 are pulled on the right side of the cow's abdomen to pull the cow's abomasum to be reduced to the right side.

[0062] See also Figure 3, Figure 4 , Figure 7 , Fig. 9 , Fig.19 and Fig. 20 A pushing piece 402a is fixed on one side of the rotating disk 402 away from the storage tube 404. The pushing piece 402a is an annular structure consisting of an inner concave reset portion and an outer convex pushing portion. The inner concave reset portion is located near the through hole 403, and the number of the inner concave reset portions is the same as the number of the through holes 403.

[0063] A line collecting assembly 9 is provided on the surface of the rotating disk 402 close to the pushing member 402a. The line collecting assembly 9 includes a line collecting wheel 901 connected to the surface of the rotating disk 402 through a rotating shaft. The line collecting wheel 901 is a hollow structure, and the line collecting wheel 901 is integrally composed of a winding drum in the middle and a wire retaining drum at both ends. A circular hole 902 is provided on the surface of the winding drum of the line collecting wheel 901 to ensure that the suture 406 can pass through the circular hole 902 and can be smoothly wound on the line collecting wheel 901. When the line collecting wheel 901 unwinds the suture 406 and rotates, it can ensure that one end of the suture 406 is led out to the outside of the protective shell 1, and the other end of the suture 406 rotates at the center of the line collecting wheel 901 to prevent the suture 406 on the outer part of the tail cover 101 from being pulled;

[0064] The suture thread 406 is wound around the winding drum of the collection wheel 901 and passes through the circular hole 902. A guide frame 903 fixed to the rotating disk 402 is provided on one side of the collection wheel 901, and a guide opening for the suture thread 406 to pass through is opened on the surface of the guide frame 903.

[0065] During specific implementation, the suture thread 406 is pulled and wound on the winding drum of the collection wheel 901. When the T-shaped push rod 502 pushes out the reset needle 405 inside the storage tube 404, the reset needle 405 will drive the suture thread 406 to be led out from the protective shell 1. At this time, the suture thread 406 will pull the collection wheel 901 to unwind, so that the suture thread 406 on the collection wheel 901 is directed out in the guide port of the guide frame 903 to prevent the suture thread 406 from being scattered during the export.

[0066] The surface of one of the wire retaining discs of the wire collecting wheel 901 is provided with ratchets distributed in a circular manner with equal angles, and the surface of the guide frame 903 near the guide port is provided with an adjustment groove, and a pawl is slidably connected to the adjustment groove through an elastic component which is not limited to a spring, and the pawl abuts against the ratchet. When the surface of one of the wire retaining discs of the wire collecting wheel 901 is provided with a ratchet, the suture 406 can be led out of the protective shell 1 along with the reset needle 405, and can drive the ratchet to squeeze the ratchet on one side of the guide frame 903, so that when the pawl slides away from the ratchet through the elastic component, the wire collecting wheel 901 can realize the forward rotation and unwinding of the suture 406, and when the ratchet is pressed away from the ratchet, the wire retaining disc on one side of the wire collecting wheel 901 will not be restricted by the ratchet, so that the suture 406 can be wound up when the wire collecting wheel 901 is reversed, and after the ratchet is released, the ratchet on one side of the wire collecting wheel 901 will abut against the ratchet to prevent the wire collecting wheel 901 from being reversed and loosened after the suture 406 is wound up.

[0067] See also Figure 4 , Figure 8 , Fig.16 and Fig.17 The outer side of the positioning channel 801 is docked with a mounting seat 804, and a sliding frame seat 802 is installed on the side of the support 3 close to the pushing member 402a. The side edge of the sliding frame seat 802 close to the rotating disk 402 is provided with a right-angle opening for the pushing member 402a to rotate through. When the pushing member 402a rotates to push the positioning channel 801 to reciprocate and telescopically slide in the sliding frame seat 802, the pushing member 402a will pass through the right-angle opening of the sliding frame seat 802, ensuring that the pushing member 402a can push the positioning channel 801 to achieve reciprocating movement. Smooth straight rods are arranged in the reserved grooves on both sides of the inner wall of 802, and support springs 803 are sleeved on the outer side of the smooth straight rods. Both ends of the mounting seat 804 are slidably connected with the smooth straight rods. The rotating axis of the line collecting wheel 901 is arranged on the inner side of the convex pushing portion of the pushing member 402a, and the outer edge diameter of the convex pushing portion of the pushing member 402a is larger than the diameter of the line retaining disk of the line collecting wheel 901, so that when the pushing member 402a squeezes the positioning channel 801 through the convex pushing portion to move, the line collecting wheel 901 and the positioning channel 801 are prevented from causing motion interference.

[0068] In specific implementation, when the cylinder 2 drives the T-shaped push rod 502 to retract into the positioning channel 801 through the guide frame 501, the direction adjustment column 504 drives the rotating disk 402 to rotate, and the rotating disk 402 drives the outer convex pushing part of the pushing member 402a to squeeze the positioning channel 801, so that the positioning channel 801 drives the mounting seat 804 to slide on the smooth straight rod in the sliding frame seat 802, so that the mounting seat 804 squeezes the supporting spring 803, ensuring that the positioning channel 801 drives the T-shaped push rod 502 away from the rotating disk 402, and at the same time, one end of the T-shaped push rod 502 slides along the guide frame 501, which can prevent the T-shaped push rod 502 from being limited by the cylinder 2 when it is away from the rotating disk 402;

[0069] When the steering column 504 drives the rotating disk 402 to rotate a predetermined angle, the supporting spring 803 will drive the positioning channel 801 to reset to the outer edge of the concave reset portion of the pushing member 402a, ensuring that the positioning channel 801 corresponds to the through hole 403 on the rotating disk 402 again. At this time, starting the driving mechanism 5 can complete the ejection operation of the next temporarily stored reset needle 405. The driving mechanism 5, the positioning component 8 and the wire gathering component 9 can be used in conjunction to ensure that when the reset needle 405 is switched to pierce the cow's abdomen, the positioning component 8 can be used to guide the ejection of the ejection needle 405, and the wire gathering component 9 can be used to follow the ejection of the reset needle 405 without obstruction.

[0070] See also Figure 7-Figure 9 and Fig.18 A notch 404a is provided on one side of the storage tube 404 close to the rotating disk 402, and the notch 404a is communicated with the inner cavity of the storage tube 404, and an annular notch 405a is provided on the outer peripheral side of the tail of the reset needle 405; a limiting mechanism 6 is provided on the surface of the rotating disk 402 close to the storage tube 404, and the limiting mechanism 6 includes a fixed block 601 fixed on the surface of the rotating disk 402, a tension spring 602 is fixed on the fixed block 601, and a clamping plate 603 is fixed at one end of two adjacent tension springs 602, and the clamping plate 603 is docked in the notch 404a on one side of the storage tube 404.

[0071] In specific implementation, when the sterilized reset needle 405 is inserted into the storage tube 404, the tail of the reset needle 405 will squeeze the clamping plate 603, so that the two ends of the clamping plate 603 stretch the tension spring 602, so that the clamping plate 603 slides along the notch 404a on one side of the storage tube 404. When the reset needle 405 is inserted into place, the tension spring 602 will pull the clamping plate 603 to clamp into the annular notch 405a at the tail of the reset needle 405, thereby ensuring that the reset needle 405 is restricted and clamped in the storage tube 404, preventing the reset needle 405 from shaking in the protective shell 1, and preventing the reset needle 405 from detaching from the storage tube 404 from the through hole 403 of the rotating disk 402. The reset needle 405 can be limited and stored through the cooperation of the limiting mechanism 6 and the needle storage mechanism 4.

[0072] In summary, when performing a displacement operation on the left side of the bovine abomasum, the endoscopic probe 106 at the front end of the protective shell 1 is used to shoot and record the inside of the bovine abdomen, and the endoscopic handheld device 105 can be used for observation, which is convenient for surgical operations. The endoscopic probe 106 and the endoscopic handheld device 105 are basic components of an external endoscope. This is a prior art, and its principle is not elaborated in detail. The throttle valve 104 on the handheld operation control handle 103 is used to adjust the speed of air intake, thereby adjusting the extension speed of the cylinder 2, and can control the opening and closing of the air source. After shaving, cleaning and disinfecting the position of the reset needle 405 to be inserted into the right abdomen of the cow, the protective shell 1 loaded with the reset needle 405 is pushed into the cow's abdomen and passes under the cow's rumen, and the head of the protective shell 1 is placed against the right abdomen of the cow. When the protective shell 1 is aligned to the correct position, the gas source is turned on, so that the T-shaped push rod 502 pushes the reset needle 405 to drive the tied and knotted suture 406 to pierce the cow's abdomen, and all the reset needles 405 drive the suture 406 to be led out from the right side of the cow's abdomen, and the reset device is taken out from the left side of the cow's abdomen, and the suture 406 is sutured with the omentum of the cow's abomasum, and finally all the sutures 406 are pulled on the right side of the cow's abdomen to pull the cow's abomasum to reset to the right side. After completing the operation of resetting the cow's abomasum to the right side, the suture 406 is cut, and the surgical site of the cow's abdomen is disinfected and sutured.
