Wherein, the soft tissue thickness measurer 100 can measure the thickness of the intestinal tissue; the soft tissue thickness gauge 100 may also measure the thickness of stomach tissue. The outer diameter of the fixing member 134 is slightly smaller than the inner diameter of the cylinder 110.
As shown in fig. 4, 6, 8 and 10, in order to better measure the thickness of the soft tissue, the clamping assembly 120 further includes a clamping shaft 123, one ends of the first clamping member 121 and the second clamping member 122 close to the driving rod 132 are respectively provided with a first sliding slot 1211 and a second sliding slot 1221, and the first sliding slot 1211 and the second sliding slot 1221 are obliquely arranged; the first clamping member 121 and the second clamping member 122 are rotatably arranged on the top of the cylinder 110 through a clamping shaft 123; one end of the driving shaft 131 is disposed in the first sliding groove 1211, and the other end of the driving shaft 131 is disposed in the second sliding groove 1221. The driving shaft 131 may slide or rotate within the first and second slide grooves 1211 and 1221. The widths of the first and second sliding grooves 1211 and 1221 are slightly larger than the diameter of the driving shaft 131. To further achieve the simultaneous driving of the opening or closing of the first and second grippers 121 and 122, the first and second chutes 1211 and 1221 are disposed obliquely with respect to the axis of the cylinder 110. The inclination angles between the first runner 1211 and the second runner 1221 and the radial lines in the bottom axial center and the top axial center directions of the cylinder 110 are acute angles; as shown in fig. 14, when the inclination angles between the first chute 1211 and the second chute 1221 and the radial line of the bottom axial center and the top axial center of the cylinder 110 are acute angles, the driving rod 132 is pushed forward to drive the first clamping member 121 and the second clamping member 122 to measure the thickness of the soft tissue. When the inclination angles between the first runner 1211 and the second runner 1221 and the radial lines in the bottom axial center direction and the top axial center direction of the cylinder 110 are acute angles, the driving rod 132 is pushed forward to drive the first clamping member 121 and the second clamping member 122 to measure the thickness of the soft tissue. In order to realize the synchronous opening and closing of the first clamping piece 121 and the second clamping piece 122, the first clamping piece 121 and the second clamping piece 122 are identical in structure and are symmetrically arranged; first clamp 121 and second clamp 122 are centrosymmetric about the axis of barrel 110, i.e., first clamp 121 can coincide with second clamp 122 by rotating about the axis of barrel 110.
As shown in fig. 15, in the second embodiment of the present invention, the inclination angles between the first chute 1211 and the second chute 1221 and the radial lines in the bottom axial center and the top axial center directions of the cylinder 110 may be obtuse angles.
Specifically, in the third embodiment of the present invention, as shown in fig. 16, in order to better measure the thickness of the soft tissue, the clamping assembly 120 further includes a clamping shaft 123, a first sliding slot 1211 and a second sliding slot 1221 are respectively formed in the middle portions of the first clamping member 121 and the second clamping member 122, and the first sliding slot 1211 and the second sliding slot 1221 are obliquely arranged; the clamping shaft 123 passes through the first chute 1211 and the second chute 1221 and both ends of the clamping shaft 123 are fixed to the top of the cylinder 110; one end of the first clamping member 121 adjacent to the driving rod 132 is rotatably connected to one end of the driving shaft 131, and one end of the second clamping member 122 adjacent to the driving rod 132 is rotatably connected to the other end of the driving shaft 131. After clamping, the clamping device can slide or rotate in the first slide groove 1211 and the second slide groove 1221. The widths of the first and second sliding grooves 1211 and 1221 are slightly larger than the diameter of the clamping shaft 123. To further achieve the simultaneous driving of the opening or closing of the first and second grippers 121 and 122, the first and second chutes 1211 and 1221 are disposed obliquely with respect to the axis of the cylinder 110. The inclination angles between the first runner 1211 and the second runner 1221 and the radial lines in the bottom axial center and the top axial center directions of the cylinder 110 are acute angles; the thickness of the soft tissue can be measured by pushing drive rod 132 forward to bring first clamping member 121 and second clamping member 122 together. In order to realize the synchronous opening and closing of the first clamping piece 121 and the second clamping piece 122, the first clamping piece 121 and the second clamping piece 122 are identical in structure and are symmetrically arranged; first clamp 121 and second clamp 122 are centrosymmetric about the axis of barrel 110, i.e., first clamp 121 may coincide with second clamp 122 by rotating about the axis of barrel 110.
As shown in fig. 10, for more precise measurement of soft tissue, the first clamping member 121 includes a driving portion 171, a rotating portion 172, a connecting portion 173 and a clamping portion 174, which are sequentially connected from the driving assembly 130 to a direction away from the driving rod 132; the second clamping member 122 comprises a driving portion 171, a rotating portion 172, a connecting portion 173 and a clamping portion 174 which are sequentially connected from the driving assembly 130 to a direction away from the driving rod; the connection portion 173 of the first clamping member 121 and the connection portion 173 of the second clamping member 122 form a clamping space 181. When the soft tissue thickness is not measured, the clamping portion 174 of the first clamping member 121 and the clamping portion 174 of the second clamping member contact each other. When the measurement of the soft tissue thickness is started, gripping portion 174 of first gripper 121 and gripping portion 174 of the second gripper are out of contact.
As shown in fig. 6 and 8, in order to make the opening angle of the first clamping member 121 and the second clamping member 122 larger, a slot 112 perpendicular to the rotation direction of the clamping assembly 120 is formed on one end of the cylinder 110 close to the clamping assembly 120, and the depth of the slot 112 is greater than the length of the driving portion 171; that is, the distance from the driving shaft 131 to the bottom of the slot 112 is greater than the distance from the driving shaft 131 to the end of the driving part 171 near the driving assembly 130.
As shown in fig. 1, 2 and 5, in order to better hold the cylinder 110, the cylinder 110 includes a rotation shaft fixing member 113, a connection cylinder 114 and a holding member 115 which are sequentially arranged; the clamping shaft 123 and the slot 112 are arranged on the rotating shaft fixing part 113; the driving assembly 130 passes through the grip 115, one end of the connecting cylinder 114 is detachably connected to the rotation shaft fixing member 113, and the other end of the connecting cylinder 114 is detachably connected to the grip 115. The shaft fixing member 113 is formed with a through hole for passing through and defining the driving rod 132. The diameter of the through hole is slightly larger than that of the driving rod.
Specifically, the diameter of the clamping assembly 120 of the soft tissue thickness gauge 100 when undeployed is less than 5mm, and the diameter of the barrel 110 of the soft tissue thickness gauge 100 is less than 5 mm. When the soft tissue thickness measurer 100 is used, the whole diameter is small, so that the soft tissue thickness measurer can directly enter the abdominal cavity through the puncture outfit.
As shown in fig. 2, in order to accurately measure the thickness of the soft tissue of the digestive tract, one end of the distance measuring piece 140 is disposed in the distance measuring bar hole 111, and a thickness scale line 142 is disposed at one side of the distance measuring bar hole 111.
As shown in fig. 3, in order to better hold the driving assembly 130, the driving assembly 130 further includes a driving member 135, and the driving rod 132 is detachably connected to the driving member 135 after passing through the barrel 110.
In the first embodiment of the present invention, when the driving shaft is disposed in the first runner 1211 and the second runner 1221, and the inclination angles between the first runner 1211 and the second runner 1221 and a radial line of the bottom axial center and the top axial center direction of the cylinder 110 are acute angles (the positional relationship between the first runner 1211 on the first clamping member 121 and the second runner 1221 of the second clamping member 122 is shown in fig. 14); when a doctor needs to measure the thickness of the soft tissue of the alimentary tract, the front ends of the first clamping piece 121 and the second clamping piece 122 are closed, and the doctor puts the front end of the soft tissue thickness measurer 100 deep into the alimentary tract; then, the doctor holds the grip 115 with one hand and the driving member 135 with the other hand (if necessary, through a certain training, the doctor can operate with one hand without holding the grip 115 and the driving member 135 with both hands; then, the driving element 135 is pushed towards the front end of the soft tissue thickness measuring device 100, the fixing element 134 moves forward through the transmission of the driving rod 132, at this time, the spring 133 is stretched, and the fixing element 134 drives the distance measuring element 141 to move forward; the driving rod 132 drives the driving shaft 131 to move forward under the combined action of the outer surface of the fixing member 134 and the inner surface of the cylinder 110; while the driving shaft 131 moves forward, the driving shaft 131 drives the first clamping member 121 to rotate through the first sliding slot 1211, and the driving shaft 131 drives the second clamping member 122 to rotate through the second sliding slot 1221; the driving shaft 131 moves from the rear ends of the first and second chutes 1211 and 1221 to the front ends of the first and second chutes 1211 and 1221 at the positions of the first and second chutes 1211 and 1221; the clamping portion 174 of the first clamping member 121 and the clamping portion 174 of the second clamping member 122 form an opening. The grip part 174 of the first grip 121 and the grip part 174 of the second grip 122 are placed on both sides of the digestive tract soft component, respectively. Then the driving member 135 is released, the first clamping member 121 and the second clamping member 122 are under the action of the stretching elastic force of the spring 133, the clamping portion 174 of the first clamping member 121 and the clamping portion 174 of the second clamping member 122 approach each other, the distance measuring member 141 moves backwards, and the clamping portion 174 of the first clamping member 121 and the clamping portion 174 of the second clamping member 122 respectively apply pressure to both sides of the digestive tract soft component; when the pressure on the two sides of the alimentary tract soft assembly reaches a certain pressure, the clamping part 174 of the first clamping piece 121 and the clamping part 174 of the second clamping piece 122 stop moving, and the distance measuring piece 141 stops moving; under the action of pressure, the tissue is compressed, and the thickness of the tissue obtained at this time is consistent with the state of anastomosis. At this time, the distance measuring member 141 fixed on the pushing rod indicates the specific thickness of the tissue on the thickness scale mark 142 on the cylinder 110, which can be directly read by the doctor, and then the proper type of the nail bin is selected. Of course, after the doctor reads the thickness of the soft tissue of the digestive tract, the doctor holds the holding member 115 with one hand and the driving member 135 with the other hand (if necessary, through a certain training, the doctor can operate with one hand without holding the holding member 115 and the driving member 135 with two hands respectively; the doctor can touch the driving member 135 with the palm of one hand, and the middle finger and the index finger of the hand hook the holding member 115); the drive member 135 is then advanced toward the distal end of the soft tissue thickness gauge 100, the first and second holding members 121, 122 are moved away from the surface of the alimentary tract soft tissue, and the surgeon removes the soft tissue thickness gauge 100 from the patient. The distance that the distance measuring member 141 moves is positively correlated with the distance between the clamping portion 174 of the first clamping member 121 and the clamping portion 174 of the first clamping member 122.
In the second embodiment of the present invention, when the driving shaft is disposed in the first slide groove and the second slide groove, and the inclination angles between the first slide groove 1211 and the second slide groove 1221 and the radial line of the bottom axial center and the top axial center direction of the cylinder 110 may be an obtuse angle (the positional relationship between the first slide groove 1211 on the first clamping member 121 and the second slide groove 1221 of the second clamping member 122 is shown in fig. 15); when a doctor needs to measure the thickness of the soft tissue of the alimentary tract, the front ends of the first clamping piece 121 and the second clamping piece 122 are closed, and the doctor puts the front end of the soft tissue thickness measurer 100 deep into the alimentary tract; then, the doctor holds the grip 115 with one hand and the drive member 135 with the other hand (if necessary, through a certain training, the doctor can operate with one hand without holding the grip 115 and the drive member 135 with both hands; the doctor can touch the drive member 135 with the palm of one hand, and the middle finger and the index finger of the one hand catch the grip 115); then the driving element 135 is pulled towards the rear end of the soft tissue thickness measuring device 100, the fixing element 134 moves backwards through the transmission of the driving rod 132, at the moment, the spring 133 is compressed, and the fixing element 134 drives the distance measuring element 141 to move backwards; the driving rod 132 drives the driving shaft 131 to move backward under the combined action of the outer surface of the fixing member 134 and the inner surface of the cylinder 110; while the driving shaft 131 moves backward, the driving shaft 131 rotates the first clamping member 121 through the first slide groove 1211, the driving shaft 131 rotates the second clamping member 122 through the second slide groove 1221, and the driving shaft 131 moves from the front ends of the first slide groove 1211 and the second slide groove 1221 to the rear ends of the first slide groove 1211 and the second slide groove 1221 at the positions of the first slide groove 1211 and the second slide groove 1221; the clamping portion 174 of the first clamping member 121 and the clamping portion 174 of the second clamping member 122 form an opening. The grip part 174 of the first grip 121 and the grip part 174 of the second grip 122 are placed on both sides of the digestive tract soft component, respectively. Then, the driving member 135 is released by one hand, the first clamping member 121 and the second clamping member 122 are under the compression elastic force of the spring 133, the clamping portion 174 of the first clamping member 121 and the clamping portion 174 of the second clamping member 122 approach each other, the distance measuring member 141 moves forward, and the clamping portion 174 of the first clamping member 121 and the clamping portion 174 of the second clamping member 122 respectively apply pressure to both sides of the digestive tract soft component; when the pressure on the two sides of the alimentary tract soft assembly reaches a certain pressure, the clamping part 174 of the first clamping piece 121 and the clamping part 174 of the second clamping piece 122 stop moving, and the distance measuring piece 141 stops moving; under the action of pressure, the tissue is compressed, and the thickness of the tissue obtained at this time is consistent with the state of anastomosis. At this time, the distance measuring member 141 fixed on the pushing rod indicates the specific thickness of the tissue on the thickness scale mark 142 on the cylinder 110, which can be directly read by the doctor, and then the proper type of the nail bin is selected. Of course, after the doctor reads the thickness of the soft tissue of the digestive tract, the doctor holds the holding member 115 with one hand and the driving member 135 with the other hand (if necessary, through a certain training, the doctor can operate with one hand without holding the holding member 115 and the driving member 135 with two hands respectively; the doctor can touch the driving member 135 with the palm of one hand, and the middle finger and the index finger of the hand hook the holding member 115); the driving member 135 is then pulled toward the rear end of the soft tissue thickness gauge 100, the first and second holding members 121 and 122 are moved away from the soft tissue surface of the digestive tract, and the doctor removes the soft tissue thickness gauge 100 from the patient. The distance moved by the distance measuring member 141 is positively correlated to the distance between the clamping portion 174 of the first clamping member 121 and the clamping portion 174 of the first clamping member 122.
In the third embodiment of the present invention, when the clamping shaft 123 passes through the first chute 1211 and the second chute 1221, and the inclination angles between the first chute 1211 and the second chute 1221 and the radial lines in the bottom axial center and the top axial center directions of the cylinder 110 are acute angles (the positional relationship between the first chute 1211 on the first clamping member 121 and the second chute 1221 of the second clamping member 122 is shown in fig. 16); when a doctor needs to measure the thickness of the soft tissue of the alimentary tract, the front ends of the first clamping piece 121 and the second clamping piece 122 are closed, and the doctor puts the front end of the soft tissue thickness measurer 100 deep into the alimentary tract; then, the doctor holds the grip 115 with one hand and the drive member 135 with the other hand (if necessary, through a certain training, the doctor can operate with one hand without holding the grip 115 and the drive member 135 with both hands; the doctor can touch the drive member 135 with the palm of one hand, and the middle finger and the index finger of the one hand catch the grip 115); then, the driving element 135 is pushed towards the front end of the soft tissue thickness measuring device 100, the fixing element 134 moves forward through the transmission of the driving rod 132, at the moment, the spring 133 is stretched, and the fixing element 134 drives the distance measuring element 141 to move forward; the driving rod 132 drives the driving shaft 131 to move forward under the combined action of the outer surface of the fixing member 134 and the inner surface of the cylinder 110; while the driving shaft 131 moves forward, the driving shaft 131 rotates the first clamping member 121 and the second clamping member 122 around the driving shaft 131, and the clamping portion 174 of the first clamping member 121 are out of contact by the pushing of the driving shaft 131 and the sliding of the clamping shaft 123 in the first slide slot 1211 and by the pushing of the driving shaft 131 and the sliding of the clamping shaft 123 in the second slide slot 1221, so that the first clamping member 121 and the second clamping member 122 are opened. The clamping shaft 123 moves from the rear ends of the first and second slide grooves 1211 and 1221 to the front ends of the first and second slide grooves 1211 and 1221 at the positions of the first and second slide grooves 1211 and 1221; the clamping portion 174 of the first clamping member 121 and the clamping portion 174 of the second clamping member 122 form an opening. The grip part 174 of the first grip 121 and the grip part 174 of the second grip 122 are placed on both sides of the digestive tract soft component, respectively. Then the driving member 135 is released, the first clamping member 121 and the second clamping member 122 are under the action of the stretching elastic force of the spring 133, the clamping portion 174 of the first clamping member 121 and the clamping portion 174 of the second clamping member 122 approach each other, the distance measuring member 141 moves backwards, and the clamping portion 174 of the first clamping member 121 and the clamping portion 174 of the second clamping member 122 respectively apply pressure to both sides of the digestive tract soft component; when the pressure on the two sides of the alimentary tract soft assembly reaches a certain pressure, the clamping part 174 of the first clamping piece 121 and the clamping part 174 of the second clamping piece 122 stop moving, and the distance measuring piece 141 stops moving; under the action of pressure, the tissue is compressed, and the thickness of the tissue obtained at this time is consistent with the state of anastomosis. At this time, the distance measuring member 141 fixed on the pushing rod indicates the specific thickness of the tissue on the thickness scale mark 142 on the cylinder 110, which can be directly read by the doctor, and then the proper type of the nail bin is selected. Of course, after the doctor reads the thickness of the soft tissue of the digestive tract, the doctor holds the holding member 115 with one hand and the driving member 135 with the other hand (if necessary, through certain training, the doctor can operate with one hand without holding the holding member 115 and the driving member 135 with two hands respectively; the doctor can touch the driving member 135 with the palm of one hand, and the middle finger and the index finger of the hand hook the holding member 115); the driving member 135 is then advanced toward the front end of the soft tissue thickness gauge 100, the first and second holding members 121 and 122 are moved away from the soft tissue surface of the digestive tract, and the doctor takes the soft tissue thickness gauge 100 out of the patient. The distance that the distance measuring member 141 moves is positively correlated with the distance between the clamping portion 174 of the first clamping member 121 and the clamping portion 174 of the first clamping member 122.
According to the technical scheme, the cylinder body 110, the clamping component 120, the driving component 130 and the distance measuring component are adopted, so that the tissue thickness of the tissue under the optimal anastomosis pressure is accurately measured; the method helps a doctor to select the staple cartridge quickly and reasonably, provides accurate objective basis for reasonably selecting the staple cartridge model of the anastomat by the doctor before the operation, enables the operation flow of the anastomat to be more standardized, reduces participation of individual subjective factors, and reduces the probability of serious complications caused by improper staple selection.
