Abstract
Description
Technical Field
[0001] The invention relates to the technical field of lip gland biopsy, in particular to a lip gland biopsy device. Background Art
[0002] Labial gland biopsy is a biopsy of the labial gland, which is a pathological examination of microscopic analysis of part of the labial gland lobule biopsy under local anesthesia. Labial gland biopsy is one of the important objective indicators for diagnosing Sjögren's syndrome, and the method is sensitive and specific.
[0003] The existing lip gland biopsy operation is relatively simple. The doctor fixes the lips with his left hand and makes a small incision with a scalpel in his right hand. The gland will be exposed, and the gland will be lifted up with tweezers. Sometimes, a blade will be used to separate it from the side, and finally the gland will be cut off with small scissors. It is often difficult to control the strength of the tweezers when clamping the lip gland tissue. Too heavy will squeeze the tissue specimen, and too light will easily fall off. After the lip mucosa is cut, the rice-sized lip gland tissue is arranged like peeled grapefruit petals. Each lip gland tissue has a separate root. During the operation, the left hand is fixed again, and the cutting work is basically completed by the right hand. However, it is not convenient to switch instruments in one hand, and the surrounding tissue may be injured during the cutting process. For this reason, we propose a lip gland biopsy device.

Since the other side of the outer teeth is a plane and matches the inner side of the end of the spring claw, the outer side of the spring claw corresponds to the arc of the outer teeth, so that the angle between the first clamping handle and the second clamping handle can only become smaller, and then the damping ring is driven again to slide a small distance along the column, and the first locking plate is rotated to fix the damping ring on the column. In this way, when the first clamping handle and the second clamping handle are manually operated with one hand, the first clamping handle and the second clamping handle are prevented from being manually stretched open, so that the area of the gland clamped by the two clamping heads is increased, thereby increasing the cutting position of the gland, thereby causing unnecessary harm to the patient. At the same time, the relative rotation of the first clamping handle and the second clamping handle can maintain the force of the clamping head to clamp the gland, and the clamping force between the clamping heads can be clamped, so that the gland remains stable when the clamping head pulls; When the internal threaded drum is rotating, the second screw rod moves in a straight line, allowing the connecting rope to pull the fixed block to rotate on the rotating seat, and the rotating seat drives the first gear to rotate during the rotation. When the first gear rotates, the second gear rotates, so that the connecting rod drives the cutter to remove the gland. Since the overall angle of the connecting rod is °, during the rotation of the connecting rod, the bottom of the connecting rod will tend to press downward. After the side of the cutter contacts the lip, since the lip is elastic, after the gland is exposed, the cutter is easier to move to a deeper layer at the bottom of the gland, which makes it easier for the cutter to remove the gland more thoroughly, thereby improving the accuracy of the operation.

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0020] See also Figure 1-Figure 9The present invention provides a technical solution: a lip gland biopsy device, comprising a column 1, a damping ring 102 is slidably connected to the column 1, a first locking disk 103 is threadedly connected to one side of the damping ring 102, the damping ring 102 is fixedly connected to the column 1 through the first locking disk 103, a sliding shaft 101 is connected to the damping ring 102 in a sliding and locking manner, a barrel shaft 105 is fixedly connected to the sliding shaft 101, a first clamping handle 5 is rotatably connected to the barrel shaft 105, a second clamping handle 6 is rotatably connected to the barrel shaft 105 near the bottom of the first clamping handle 5, a clamping head 506 is fixedly connected to one end of the first clamping handle 5 and the second clamping handle 6, the upper and lower ends of the barrel shaft 105 are fixedly connected to a fixed disk 104, a rack disk 10 is fixedly installed on the fixed disk 104, a slide groove 11 is fixedly installed at the bottom of the first clamping handle 5 and the top of the second clamping handle 6, and a second clamping head 506 is fixedly connected to the inner side of the slide groove 11 A spring 12, one end of the first spring 12 is fixedly connected with a slider 13, the slider 13 is slidably connected with the slide groove 11, and the slider 13 is rotatably connected with a pair of spring claws 15 at one end facing the rack plate 10, and the end of the spring claw 15 is meshed with the rack plate 10, and a second spring 16 is fixedly connected between each spring claw 15 and the slider 13; one side of the clamping head 506 is arched outward, and the inner side is recessed downward to form an arc surface, and the bottom of the clamping head 506 is in a pointed cone shape. When the device is used, a small incision is first made on the patient's lips with a scalpel, and then the first clamping handle 5 and the second clamping handle 6 are manually held with one hand, and the first clamping handle 5 and the second clamping handle 6 are pinched or relaxed to adjust, so that the pair of clamping heads 506 are aligned with the gland, and then adjusted up and down on the outside of the column 1 through the damping ring 102, and finally the first locking disk 103 is tightened, and then the patient is operated on. The specific operation method is as follows: The outer edge of the rack plate 10 has multiple external teeth, and one side of each external tooth is in the shape of an arc, and the other side of the external tooth is a plane. Each spring claw 15 has a bent portion at one end, so that the two vertical surfaces of the spring claw 15 can form an outer side close to the slider 13 and an inner side close to the external teeth of the rack plate 10. The outer side of the spring claw 15 and the external teeth of the rack plate 10 have arc-shaped side contact.
[0021] The other end of the slider 13 is rotatably connected to the turntable 14, and the inner circle of the turntable 14 is threadedly connected to the first screw rod 18, one end of the first screw rod 18 is fixedly connected to the limit block 17, the first screw rod 18 and the slider 13 are movably connected, and a driving groove 1701 is provided on the limit block 17, and a protrusion is provided at the bottom of the elastic claw 15 at the highest point and the top of the elastic claw 15 at the lowest point, and the protrusion is consistent with the driving groove 1701, so that the limit block 17 controls the elastic claw 15 to hinge on the slider 13 through the driving groove 1701, wherein when the protrusion of the elastic claw 15 slides on the driving groove 1701, the limit block 17 can drive the elastic claw 15 to hinge on the slider 13. It is worth mentioning that when the turntable 14 is manually rotated, the first screw rod 18 It moves linearly inside the slider 13, so the limit block 17 can be close to or away from the outer teeth of the rack plate 10. When the end of the limit block 17 is tightly pressed against the rack plate 10, because the contact area between the outer teeth of the rack plate 10 and the limit block 17 is relatively large, the limit block 17 cannot be separated from the outer teeth of the rack plate 10 by rotating the first clamping handle 5. Even with the first spring 12, the first spring 12 will not produce outward stretching, so that the limit block 17 can be locked on the outer teeth of the rack plate 10. Therefore, the relative position between the first clamping handle 5 and the second clamping handle 6 is locked. Therefore, after the two clamping heads 506 are attached to the gland, the turntable 14 can be manually rotated so that the limit block 17 is located between the two outer teeth of the rack plate 10, and then rotated again. The first locking disk 103 slides the damping ring 102 down along the column 1, allowing the two clamping heads 506 to dock with the gland, and then the turntable 14 is rotated again to make the limit block 17 disengage from the two outer teeth of the rack plate 10, so that the contact area between the limit block 17 and the outer teeth of the rack plate 10 is reduced, and the first clamping handle 5 and the second clamping handle 6 can move relatively, so that when the protrusion of the spring claw 15 is located in the middle of the driving groove 1701, the limit block 17 drives the spring claw 15 to compress the second spring 16. After the second spring 16 is compressed, the contact area between the end of the spring claw 15 and the outer teeth of the rack plate 10 is gradually reduced. Since the other side of the outer teeth is a plane and coincides with the inner side of the end of the spring claw 15, the outer side of the spring claw 15 is in contact with the outer teeth. The arc of the teeth corresponds, so that the angle between the first clamping handle 5 and the second clamping handle 6 can only become smaller, and then the damping ring 102 is driven again to slide a small distance along the column 1, and the first locking plate 103 is rotated to fix the damping ring 102 on the column 1, so that when the first clamping handle 5 and the second clamping handle 6 are manually operated with one hand, it is prevented from being manually stretched open, so that the area of the gland clamped by the two clamping heads 506 is increased, thereby increasing the cutting position of the gland, thereby causing unnecessary harm to the patient, and at the same time, the relative rotation of the first clamping handle 5 and the second clamping handle 6 can maintain the force of the clamping head 506 to clamp the gland, and the clamping force between the clamping heads 506 can be clamped.Allowing the gland to remain stable while the clamping head 506 pulls the gland; It is worth mentioning that in order to release the restriction of the end of the spring claw 15 on the outer teeth of the rack disk 10, the turntable 14 is rotated again, and the protrusion of the spring claw 15 contacts one end of the driving groove 1701. When the turntable 14 rotates, the first screw rod 18 can still drive the limit block 17 to move, and the limit block 17 drives the spring claw 15 through the driving groove 1701 to further compress the second spring 16, so that the end of the spring claw 15 is separated from the outer teeth of the rack disk 10, so that the first clamping handle 5 and the second clamping handle 6 can move freely. When the limit block 17 is always separated from the outer teeth of the rack disk 10, this does not affect the relative movement of the first clamping handle 5 and the second clamping handle 6. The limit block 17 makes the first clamping handle 5 and the second clamping handle 6 have a sense of frustration when they move relative to each other, so that the operator has a sense of touch, prompting the user that the first clamping handle 5 and the second clamping handle 6 are working.
[0022] Furthermore, the first clamping handle 5 and the second clamping handle 6 are both provided with gland removal devices near the clamping head 506, and the other ends of the first clamping handle 5 and the second clamping handle 6 are formed into a ring structure by a bending machine, and the other ends of the first clamping handle 5 and the second clamping handle 6 (the ends of the first clamping handle 5 and the second clamping handle 6 away from the ring structure) are respectively fixedly connected with a connecting component for driving the gland removal device to work; the gland removal device includes connecting rods 23 that are rotatably connected to the first clamping handle 5 and the second clamping handle 6, and the bottom of each connecting rod 23 is fixed with a cutter 24 through a magnetic connection, and a pair of cutters 24 are stacked on each other, and the middle part of the connecting rod 23 is bent so that the cutter 24 and the clamping head 506 are connected. There is a gap, and the distance between the cutter 24 and the fixed disk 104 is smaller than the distance between the clamping head 506 and the fixed disk 104; the overall angle of the connecting rod 23 is 135°, and the movement angle of the cutter 24 does not exceed 180°; the connecting assembly includes a second gear 22 fixedly connected to the top of each connecting rod 23, and the first clamping handle 5 and the second clamping handle 6 are respectively rotatably connected to the first gear 21 at one end, and the first gear 21 and the second gear 22 are meshed for transmission. A rotating seat 20 is fixedly installed on the top of the first gear 21, and the outer ring of the rotating seat 20 is fixedly connected to the connecting rope 19; the connecting assembly also includes an internally threaded rotating cylinder 26, to which the other ends of the first clamping handle 5 and the second clamping handle 6 are rotatably connected, and the inner ring of each internally threaded rotating cylinder 26 is A second screw rod 25 is threadedly connected, and the second screw rod 25 and the connecting rope 19 are fixedly connected together. A fixing block 28 is fixedly installed on the outer ring of each rotating seat 20. A third spring 27 is fixedly connected between the first clamping handle 5 and the second clamping handle 6 and the fixing block 28. When the patient's lips are fixed by the clamping head 506, the angle between the first clamping handle 5 and the second clamping handle 6 cannot be adjusted. Therefore, the internal thread rotating cylinder 26 can be controlled by the doctor's index finger and thumb to rotate the internal thread rotating cylinder 26. During the rotation of the internal thread rotating cylinder 26, the second screw rod 25 moves in a straight line, allowing the connecting rope 19 to pull the fixing block 28 to rotate on the rotating seat 20, so that the rotating seat 20 is in the process of rotating. The first gear 21 is driven to rotate. When the first gear 21 rotates, the second gear 22 is rotated, so that the connecting rod 23 drives the cutter 24 to remove the gland. Since the overall angle of the connecting rod 23 is 135°, during the rotation of the connecting rod 23, its bottom will tend to press downward. After the side of the cutter 24 contacts the lip, since the lip is elastic, after the gland is exposed, the cutter 24 is easier to move to a deeper layer of the bottom of the gland, which makes it easier for the cutter 24 to remove the gland more thoroughly and improve the accuracy of the operation. After the gland is removed, the doctor's index finger and thumb drive the internal threaded rotating cylinder 26 to rotate in the opposite direction, reset the third spring 27, and also reset the cutter 24.
[0023] Furthermore, a mandibular frame 2 is fixedly installed at the bottom of the column 1, and a pad 3 is detachably connected to the top of one end of the mandibular frame 2. The top of the pad 3 is made of anti-slip material. When the patient undergoes a gland biopsy, the chin can be placed on the pad 3 to facilitate subsequent fixation of the lips, thereby improving the comfort of the patient and the doctor during the gland biopsy.
[0024] A mounting plate is slidably connected to the column 1, and mounting rods 4 are suspended at the bottom of both ends of the mounting plate. One end of each mounting rod 4 is fixedly connected to a connecting rod 7, and one end of the connecting rod 7 is fixedly connected to a fixing rod 801. A mounting head is fixedly installed on one end of the fixing rod 801, and a second locking disk 802 is detachably connected to the mounting head. A rotating ear 8 is rotatably connected to each mounting head, and the rotating ear 8 is fixedly connected to the mounting head through the second locking disk 802. A limiting rod 901 is fixedly connected to the bottom between the two rotating ears 8, and a movable rod 9 is movably connected to the top between the two rotating ears 8; the movable rod 9 and the limiting rod 901 are made of metal, and the ends of the movable rod 9 and the limiting rod 901 are connected to heaters. When the patient undergoes gland detection, after putting the chin on the pad 3, the doctor rotates the second locking The patient loosens the lip and places the lower lip or upper lip between the movable rod 9 and the limiting rod 901. The movable rod 9 is then manually tightened to allow the movable rod 9 and the limiting rod 901 to fix the lip. The two rotating ears 8 are then flipped over to flip the lips after the movable rod 9 and the limiting rod 901 are clamped. The second locking disk 802 is then driven again to lock the position of the rotating ears 8 after rotation, so that the clamping head 506 can clamp the gland. The heater is used for heat conduction of the movable rod 9 and the limiting rod 901, so that it is convenient to use in cold weather. The movable rod 9 and the limiting rod 901 are made of metal and can be disinfected after polishing.
