Description
Technical Field
The invention relates to a medical apparatus, in particular to a pneumoperitoneum-free supporting device used in laparoscopic surgery.
Background
Laparoscopic surgery is a newly developed minimally invasive method, is a relatively advanced surgical treatment method at present, and can treat various diseases. As an advanced minimally invasive technology, the laparoscopic surgery has small trauma, little bleeding and rapid postoperative recovery of the patient, and is widely applied in clinic at present. Traditional laparoscopic surgery utilizes CO2 pneumoperitoneum techniques to create a surgical operating space. Because CO2 pneumoperitoneum has many adverse effects on respiration, circulatory system and gestation fetus, it is not suitable for patients with poor body condition or suffering from cardiovascular and cerebrovascular diseases, embolic diseases and pulmonary insufficiency, various abdominal wall suspension devices have been developed to perform pneumoperitoneum-free laparoscopic surgery. However, the existing pneumoperitoneum-free technology uses a Kirschner wire to penetrate into the abdominal wall to suspend the abdominal wall, so that secondary wounds are easily carried out on a patient, the abdominal wall suspension tension can enable the two side abdominal walls to gather towards the middle, the extrusion intestinal canal is concentrated towards the middle, and the operation space is reduced and narrowed; when the muscle tension is larger, the operation space is obviously reduced, a 4mm incision is additionally formed due to the placement of the subcutaneous steel wire, the stress is concentrated on the suspension steel wire, the abdominal wall of a patient is easily damaged, and the formed operation space is relatively small.

FIG. 2 is a schematic view of the overall exploded construction of the present invention;
fig. 3 is a schematic perspective view of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings, for the purpose of making the objects, technical solutions and advantages of the present invention more apparent.
Referring to FIG. 1-3, a schematic structure is shown.
The invention embodiment of an umbrella type laparoscope pneumoperitoneum-free supporting device comprises a main rod 1, a movable sleeve body 2, a plurality of opening claws 3, a hinging rod 4 and a base 5.
The movable sleeve 2 is slidably provided on the main lever 1, and moves up and down along the main lever 1 under manual or mechanical driving force.
In this embodiment, six expanding claws 3 are preferably symmetrically arranged on the peripheral surface of the lower side of the movable sleeve body 2 at equal intervals, and the middle parts of the expanding claws 3 are hinged with the tail ends of the hinging rods 4.
The base 5 is fixedly arranged at the lower end of the main rod 1, a straight slot hole 51 is formed in the edge of the transition curved surface on the base 5, and a limiting hole 41 at the head end of the hinging rod 4 is hinged with the straight slot hole 51.
The head end of the hinging rod 4 is provided with a U-shaped notch groove, and the size of the straight groove hole 51 is equivalent to that of the U-shaped notch groove, so that the straight groove hole 51 can be anastomosed and folded in the U-shaped notch groove in the folding process of the invention.
When the invention is used, the six opening claws 3 are folded to be tightly attached to the main rod 1, then the main rod support is slowly and obliquely inserted into the abdominal cavity from the air charging port, the movable sleeve body 2 is driven by manpower or mechanical driving force, the hinging rod 4 supports each opening claw 3 upwards, and the main rod 1 is lifted to jack the abdomen, so that a larger operation space is formed. As shown in fig. 1, when the main rod 1 is put down, the movable sleeve 2 moves upwards along the main rod 1, and each of the expanding claws 3 is folded under the driving of the hinging rod 4, so as to further fold the bracket.
In this embodiment, the supporting jaw forms umbrella-shaped structure, six struts claw 3 360 degrees evenly distributed on the circumference, articulated pole 4 also be six and prop up claw one-to-one setting, when taut and mentioning the belly through mobile jib 1, the holding power is great and more even, laminating belly, be difficult for causing the injury to the abdominal wall, can form great operation space and operation field of vision, and prop up the contact between claw 3 and the abdominal wall and be the face contact, has more reduced traditional suspension type no pneumoperitoneoscope operation line contact to the injury of abdominal wall. Further, the main rod 1 is in a regular hexagon or other polygonal shapes, and is axially guided between the main rod 1 and the movable sleeve body 2, so that the movable sleeve body 2 can conveniently reciprocate along the main rod 1, and meanwhile, the movable sleeve body 2 is prevented from twisting along the main rod 1 when moving up and down, and the movable sleeve body 2 is good in stability when moving.
The top surface of the bottom 2 is provided with a boss 52, the lower end of the main rod 1 is provided with a groove 11 for installing the boss 52, limiting fixing holes 53 and 12 are formed between the boss 52 and the groove 11, the boss 52 and the groove 11 are fastened through the cooperation of fixing pins, the structure is stable, torsion is not easy to occur, and the installation and the cleaning are convenient.
Preferably, the base 5 is provided with a transition curved surface, when the movable sleeve body 2 moves downwards along the main rod 1, the expanding claw 3 can be slowly expanded along the transition curved surface, the received resistance is small, the expanding of the expanding claw (3) is guided by the curved surface, the expanding claw 3 is prevented from expanding to damage the structure along other directions, and the abdominal wall is further injured. As shown in fig. 3, when the movable sleeve body 2 moves upwards along the main rod 1, the opening claw 3 is folded along the transition curved surface under the driving of the hinging rod 4, the size of the hinging rod 4 is matched with the straight groove 32 opened at the lower end of the opening claw 3, and the opening claw 3 can be accommodated in the straight groove 32 of the hinging rod 4, so that the opening claw 3 is completely tightly attached to the base, the diameter is reduced to the minimum, and the abdomen is convenient to withdraw.
It should be noted that, the straight slot hole 51 on the base 5 is hinged with the limiting hole 41 at the tail end of the hinge rod 4, and the design of the straight slot hole 51 increases one degree of freedom integrally, so that the hinge rod 4 can move up and down along the hinge rod by a small extent, further the spreading claw 3 can spread to a maximum angle, and after spreading to the maximum angle, the spreading action is maintained under the blocking action at the two ends of the straight slot hole 51 and the abdominal pressure. More preferably, in the spreading process, the top of the straight slot hole 51 and the lower end surface of the spreading claw 3 limit, so that the spreading claw 3 can only be spread into a horizontal position, and the safety function is further realized.
The above disclosure is only a preferred embodiment of the present invention, and it is needless to say that the scope of the invention is not limited thereto, and therefore, the equivalent changes according to the claims of the present invention still fall within the scope of the present invention.
