Description

Technical Field

[0001] The present invention relates to the field of surgical equipment, and in particular to a traction-type abdominal wall suspension and puncture device. Background Art

[0002] During laparoscopic surgery, carbon dioxide gas needs to be continuously injected into the patient's abdominal cavity to maintain the surgical operating space. However, due to the long operation time and high pneumoperitoneum pressure, a series of serious complications may occur due to the different physical conditions of the patients, especially for infants and the elderly. Some patients with cardiovascular and pulmonary diseases are seriously endangered, and the risk of surgery and anesthesia is increased. At present, pneumoperitoneum-free laparoscopic technology mainly relies on abdominal wall suspension to form a surgical operating space, which requires the use of an abdominal wall traction device, and cooperates with the traction device to fix and support the abdomen. Clamps clamp the outer wall of the abdomen, which will cause damage to the patient for a long time. At the same time, the abdominal cavity space for suspension is limited, and it is inconvenient to clamp the abdominal wall.

[0003] Therefore, how to design a pneumoperitoneum-free surgical device that can increase the surgical space and reduce damage to patients has become a technical problem that needs to be solved urgently. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the above-mentioned prior art or related technology, and provides a traction-type abdominal wall suspension and puncture device, which can make the traction force act evenly on the inner side of the abdominal wall, reduce the patient's injury, improve the supporting force, and increase the surgical operation space.

[0005] The present invention is realized through the following technical scheme: a traction-type abdominal wall suspension and puncture device, comprising: an outer sleeve, which is a hollow tubular structure; an inner push tube, which is arranged inside the outer sleeve and is sleeved with the outer sleeve and can move along the length direction of the outer sleeve; a support rod, one end of which is hinged to the bottom of the outer sleeve and can rotate around the hinge pin under the push of the inner push tube so that the free end of the support rod can be unfolded to the outside of the outer sleeve; a puncture core, which is arranged inside the inner push tube, is sleeved with the inner push tube and can pass through the bottom of the inner push tube.

[0006] The traction-type abdominal wall suspension and puncture device provided by the present invention preferably further comprises: a magnet connected to the side wall of the support rod.

[0007] The traction-type abdominal wall suspension and puncture device provided by the present invention preferably further comprises: a hanging ear, which is arranged on the top outer side of the outer sleeve, and the top of the outer sleeve extends outward to form the hanging ear, which is used to connect the traction device.

[0008] According to the traction-type abdominal wall suspension and puncture device provided by the present invention, preferably, a plurality of hooks are evenly distributed on the outer side of the top of the outer tube, so that a plurality of traction devices can suspend the outer tube from a plurality of angles; when the traction devices are respectively connected to a plurality of symmetrical hooks, the outer tube is in a vertical state; when the traction devices are respectively connected to a plurality of asymmetrical hooks, the outer tube is in an inclined state.

[0009] According to the traction-type abdominal wall suspension and puncture device provided by the present invention, preferably, there are 6 hanging ears in total, which are evenly distributed along the circumference direction of the outer sleeve.

[0010] According to the traction-type abdominal wall suspension and puncture device provided by the present invention, preferably, the outer wall of the inner push tube is provided with threads, and the inner wall of the outer sleeve is provided with corresponding threads, so that the inner push tube can be rotated and pushed forward by means of threaded connection.

In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, the meaning of "multiple" is two or more. The terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood through specific circumstances.

[0028] like Figure 1 As shown, an embodiment of the present invention discloses a traction-type abdominal wall suspension and puncture device, comprising: an outer sleeve 3, which is a hollow tubular structure; an inner push tube 2, which is arranged inside the outer sleeve and is sleeved with the outer sleeve and can move along the length direction of the outer sleeve; a support rod 4, one end of which is hinged to the bottom of the outer sleeve and can rotate around the hinge pin under the push of the inner push tube, so that the free end of the support rod can be unfolded to the outside of the outer sleeve; a puncture core 1, which is arranged inside the inner push tube and is sleeved with the inner push tube and can pass through the bottom of the inner push tube; a magnet 5, which is connected to the side wall of the support rod.

[0029] In this embodiment, the puncture core is threadedly connected to the inner push tube; the inner push tube is threadedly connected to the outer sleeve; the support rod and the outer sleeve are hinged by a pin, a magnet is arranged inside the support rod, and the magnetic poles of the magnets of the multiple support rods attract each other, so that the multiple support rods can firmly wrap the puncture core, so that the puncture operation can be effectively performed.

[0030] like Figure 2 As shown, one embodiment of the present invention also discloses the structure of the traction-type abdominal wall suspension and puncture device in the above embodiment in the expanded state: the inner push tube moves downward through the threaded structure, so that the support rod rotates about the axis (see Figure 4The cross-sectional view shown has a certain lever arm effect). After the inner push tube is moved into place, the support rod is rotated into a horizontal state to form a support plane. After the device is lifted, the support surface forms a force relationship with the inner wall of the patient's abdominal cavity. The effect of multiple support rods will increase the force area and reduce the patient's injury.

[0031] like Figure 3 and Figure 4 As shown, an embodiment of the present invention also discloses a schematic diagram of the disassembled state of the traction-type abdominal wall suspension and puncture device of the above embodiment: when the device completes the unfolding operation, the puncture needle (puncture core) can be taken out, and the internal space of the inner push tube is the instrument channel 201, so that the surgical instrument can enter the abdominal cavity for surgical operation. It can be seen from the figure that the top of the puncture core is provided with a puncture needle connecting thread 101, and the bottom of the puncture core is a puncture needle head 102. A hanging ear is provided on the outer side of the top of the outer sleeve, and the hanging ear serves as a hoisting hole 301 of the traction device. One end of the support rod is hinged to the outer sleeve through a rotating shaft 401. After the inner push tube is in place, its bottom outer wall fits with the support rod, so that the support rod is unfolded and turned to a horizontal position to play a supporting role; when retracting the device, as long as the inner push tube is reset to the initial state, the support rod will wrap the puncture core through gravity and the suction force of the magnet, and then the device can be taken out from the abdominal cavity.

[0032] like Figure 5 and Figure 6 As shown, an embodiment of the present invention also discloses a schematic diagram of the suspension state of the traction-type abdominal wall suspension and puncture device of the above-mentioned embodiment: the traction device 7 is connected to the lifting hole 301 through a hook. When the symmetrical lifting holes are hung with the hook, the traction-type puncture device can be kept in a vertical state; and when the hook is hung in the adjacent lifting hole, the device can be tilted, changing the angle of the device; multiple hooks can also be used for lifting, which will be more stable.

[0033] like Figure 7 As shown, an embodiment of the present invention also discloses another implementation of the traction-type abdominal wall suspension and puncture device of the above embodiment: a puncture sleeve 6 is added to the outside of the outer sleeve of the above embodiment, and the magnet is installed in reverse to reverse the magnetic poles.

[0034] Specific structure such as Figure 8 and Fig. 9 As shown, the device is inserted into the abdominal cavity as a whole, and the whole consisting of the support rod, the outer sleeve, the inner push tube and the puncture core is pushed forward to the outside of the puncture sleeve. The magnets installed in the opposite direction will have a repulsive effect, causing the support rod to open a certain angle, and then after the inner push rod is rotated into place, the support rod will be unfolded into place, which is beneficial to the transmission effect of the inner push tube and reduces a certain amount of force; when the device is retracted, the inner push tube must be reset first, and then all parts are pulled out of the puncture sleeve, and finally the device is pulled out of the abdominal cavity as a whole to complete the entire operation.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
