The choke valve 2 comprises an outer ring 21, an inner ring 22 and an elastic corrugated connecting ring 23; the outer ring 21 is connected to the inner ring 22 by a corrugated connecting ring 23. The inner ring 22 is provided with a cross-shaped cut 28 in the middle.
When the surgical instrument is pulled out, the air-blocking valve can automatically close the incision by utilizing the elasticity of the air-blocking valve, so that the pressure of the pneumoperitoneum is maintained, and an operation space and a working channel are established for the surgical instrument or the endoscope. Due to the arrangement of the corrugated connecting ring with the elastic wrinkles, the puncture cone can swing in any direction at 360 degrees when penetrating through the inner ring of the air blocking valve during puncture, so that the puncture cone is convenient to find a position in an operation, is flexibly applied and ensures air tightness. The endoscope and the surgical instrument can swing in any direction of 360 degrees when passing through the inner ring of the choke valve, and the position can be found conveniently in the operation.
On the basis of the above structure, in an optional implementation case, the present embodiment is further provided with a plurality of elastic gas barrier sealing sheets 24 and a plurality of anti-pollution isolating strips 25 on the inner ring 22. The anti-pollution isolating bar 25 can effectively reduce the contact surface of the endoscope and the air blocking valve, effectively reduce the pollution of the air blocking valve 2, namely effectively reduce the occurrence of the condition that the endoscope is polluted by the air blocking valve 2 again, and further improve the smoothness of the operation.
Furthermore, the valve body comprises an annular base body 11 in a circular ring structure, and a raised sealing part 12 integrally formed with the annular base body 11; the sealing portion 12 is provided with a through hole 13 through which the puncture needle rod passes.
The seal portion 12 includes a first thin-walled portion 121 connected to the annular base body 11, a thick-walled portion 122 connected to the first thin-walled portion 121, and a second thin-walled portion 123 connected to the thick-walled portion 122; in this way, the entire thickness of the sealing portion 12 is set to be "thin" in the direction from the annular base 11 toward the through hole 125.
Specifically, the first thin-walled portion 121 and the second thin-walled portion 123 are each smaller in wall thickness than the thick-walled portion 122; and the through hole 125 is formed in the second thin-walled portion 123, that is, the through hole 125 is provided on the second thin-walled portion 123, and the hole wall of the through hole 125 at the opening away from the annular base body 11 is flanged from the inside of the through hole 125 to the outside of the through hole 125 along the circumferential direction of the through hole 125 to form an arc-shaped flange 126. For the arc-shaped turned-over edge 126, the arc-shaped opening of the arc-shaped turned-over edge 126 faces the side away from the axis of the through hole 125, and in addition, the height of the arc-shaped turned-over edge 126 along the axis direction of the through hole 125 is 0.3-1.0 mm in the embodiment.
Alternatively, the first thin-wall portion 121 and the second thin-wall portion 123 have the same wall thickness; and (d). The thickness of the thick-walled portion 122 is 1.2 to 1.6 times the thickness of the first and second thin- walled portions 121 and 123. Still alternatively, the wall thickness of the first thin-walled portion 121 and the second thin-walled portion 123 is not equal; and the thickness of the thick-walled portion 122 is 1.2 to 1.6 times the larger of the first thin-walled portion 121 and the second thin-walled portion 123. That is, the use case of the present embodiment is satisfied as long as the thickness of the first thin-walled portion 121 and the second thin-walled portion 123 is thinner than that of the thick-walled portion 122.
With the valve body of the present embodiment, the wall thickness of the integral sealing portion 12 is "thin and thin" in the direction from the annular base 11 to the through hole 125, such a structure can still effectively maintain the air tightness at the matching position with the instrument, such as the puncture needle rod, passing through the puncture outfit at the through hole 125, and the wall thickness of the "thin and thin" structure of the annular base 11 reduces the holding resistance of the integral sealing portion 12 to, for example, the puncture needle rod. In detail, when the valve body is engaged with the puncture needle rod, the sealing portion 12 needs to be engaged with the puncture needle rod to generate following deformation along with the movement of the puncture needle rod, and for the following deformation, when it is necessary to ensure good air tightness between the through hole 125 and the puncture needle rod, the through hole 125 needs to maintain good engagement and holding effect with the puncture needle rod, so that the air tightness can be not affected and the smoothness of the movement of the puncture needle rod can be improved only by the good following effect generated by the sealing portion 12 as a whole, and the good following performance of the sealing portion 12 is realized here, the wall thickness of the sealing portion 12 is subjected to thin-wall treatment, so that the wall thickness of the sealing portion 12 becomes thin, and thus the resistance of the sealing portion 12 along with the adaptive deformation of the puncture needle rod can be reduced, but the valve body also needs to maintain certain strength to prevent the damage to the sealing portion 12 along with the movement of the puncture needle rod and further the occurrence of air tightness caused by the damage of the sealing portion 12 Therefore, for the sealing portion 12 with a thinner wall thickness, a thicker wall thickness structure needs to be formed on a part of the side wall of the sealing portion 12, so that the thicker wall thickness part on the sealing portion 12 effectively ensures that the whole sealing portion 12 has a certain rigidity in addition to a good follow-up performance, and is not easily damaged.
Secondly, the arc-shaped flange 126 formed at the opening of the through hole 125 is mainly characterized in that a certain clearance exists between the puncture needle rod and the edge of the opening of the through hole 125, which is far away from the annular base body 11, when the puncture needle rod exits from the puncture outfit, from the contact surface between the inner wall of the through hole 125 and the puncture needle rod, the inner wall of the through-hole 125 contacting with the lancet rod is a smooth wall structure without edge contact, wherein the inner diameter of the portion of the through hole 125 having the inner wall in contact with the lancet shaft is adapted to fit the outer diameter of the lancet shaft, so that the inner wall of the through hole 125 of this portion forms a circumferential packing for the outer side wall of the piercing needle shaft, and the edge of the hole of the through hole 125 departing from the annular base body 11 does not contact the puncture needle rod, so that the edge of the through hole 125 departing from the hole of the annular base body 11 does not form the obstruction influence on the exit of the puncture needle rod, and the puncture needle rod can rapidly exit the valve body.
Next, the column hole matching structure includes a plurality of connection columns 301 provided with vertical protrusions at intervals along the radial direction of the protection gasket ring 300 on the side end surface of the protection gasket ring 300 facing the annular base, a plurality of column holes 201 provided on the side end surface of the swing valve ring 200 facing the fisheye ring 11 and adapted to be inserted into the plurality of connection columns 301, and through holes 101 provided in the annular base 11 and adapted to allow the plurality of connection columns 301 to pass through.
Further, the sealing body 500 includes an insertion portion 501 adapted to be inserted between the protection pad pressing ring 300 and the ring-shaped base 11, a connection portion 502 integrally connected to the insertion portion 501 to have an L-shaped structure, and a sealing portion 505 connected to the connection portion 502; the sealing portion 505 is formed by a plurality of sealing flaps in a manner of abutting or partially overlapping; the sealing portion 505 in this embodiment may be a one-piece sealing membrane having a "Y" or "cross" shaped groove, or a duckbill-shaped sealing surface formed by abutting a plurality of sealing lobes, or a sealing surface formed by overlapping four sealing lobes having a central angle greater than or equal to 90 °, where the sealing body 500 may be made of, for example, but not limited to, rubber or silicone. The insertion portion 501 has a through hole 506 adapted to pass through the plurality of connection posts 301. That is, the fitting portion 501 of the sealing body 500 is also pressed and fixed between the protection gasket 300 and the annular base body 11 by the engagement of the connection post 301 and the through hole 506.
In addition, it should be noted that, in relation to the oscillating valve 100, the oscillating body includes an annular base 31 and an S-shaped engagement portion which are integrally formed; the S-shaped engagement portion is integrally connected to the annular base body 11. The S-shaped joint part comprises a small U-shaped folding part 34 connected with the annular base body 11 and a large U-shaped folding part 32 connected with the annular base platform 31; wherein the opening of the small U-shaped fold 34 is opposite the seal 12; and the opening of the large U-fold 32 is directed towards the seal 12. For the oscillating body of the present embodiment, the oscillating body and the valve body are made of a material having a certain elasticity, such as but not limited to medical polymer plastic, rubber, or silica gel, wherein the medical polymer plastic is, for example, medical polytetrafluoroethylene, so that the oscillating body presents good following performance along with the movement of the puncture needle rod through the elastic matching of the material and the S-shaped engagement portion.
Further in detail with reference to the drawings, the small U-fold 34 shares a side wall with the large U-fold 32; and the large U-fold 32 projects from the annular abutment 31 at the end facing away from the seal portion 12. Theoretically, the distortion of the S-shaped engagement portion formed by the small U-folded portion 34 and the large U-folded portion 32 is affected by the height of the small U-folded portion 34 in the axial direction of the ring base 31 and the height of the large U-folded portion 32 in the axial direction of the ring base 31, i.e., the greater the height in the axial direction of the ring base 31, the greater the space for distortion of the S-shaped engagement portion. However, in consideration of the consideration of reducing the influence of the too high height of the small U-shaped folded portion 34 along the axial direction of the annular base 31 on the movement of the valve body along with the puncture needle rod while effectively ensuring the distortion space of the S-shaped engagement portion, the small U-shaped folded portion 34 designed in this embodiment has a smaller height along the axial direction of the annular base 31 than the large U-shaped folded portion 32. Namely, the height of the large U-shaped folded part 32 along the axial direction of the annular base 31 is fully utilized to provide a relatively large distortion space for the S-shaped joint part, and the height of the small U-shaped folded part 34 along the axial direction of the annular base 31 is controlled in combination with the provision of the distortion space for the S-shaped joint part and the reduction of the influence on the follow-up of the valve body relative to the puncture needle rod.
Finally, it should be noted that, for the distortion of the S-shaped connection portion, besides the height of the small U-shaped folded portion 34 along the axial direction of the annular base 31 and the height of the large U-shaped folded portion 32 along the axial direction of the annular base 31, the distance between the two side walls of the small U-shaped folded portion 34 and the distance between the two side walls of the large U-shaped folded portion 32 can also be influenced, and here, the distance between the two side walls of the small U-shaped folded portion 34 and the distance between the two side walls of the large U-shaped folded portion 32 can be the same or different, for example, by designing the distance between the two side walls of the small U-shaped folded portion 34 to be larger than the distance between the two side walls of the large U-shaped folded portion 32, so as to compensate for the height of the small U-shaped folded portion 34 along the axial direction of the annular base 31 to be smaller than the height of the large U-shaped folded portion 32 along the axial direction of the annular base 31, this improves the contribution of the small U-folded portion 34 to the distortion of the S-shaped joint portion.
