At present, when laparoscopic minimally invasive surgery is performed, due to the limitation of laparoscopic minimally invasive surgery, particularly the far-end rectum of laparoscopic minimally invasive surgery is narrow in space, the operation difficulty in the surgery is increased, a minimally invasive incision needs to be added to the lower abdomen, and other auxiliary tools are used for pulling, separating and lifting the tissues at the abdominal cavity of a patient, so that an intracavity cutting anastomat is easily clamped to the optimal tissue cutting and suturing position, but the operation is complicated, the difficulty is increased, the pain of the patient is increased, the operation time is prolonged, the operation cost is increased, and the operation visual field has certain limitation.
Disclosure of Invention
The invention aims to provide an intestinal canal retractor aiming at the defects, tissues at the abdominal cavity part of a patient can be pulled, separated and lifted through a natural channel of a human body in the operation process, so that an intracavity cutting anastomat can be easily clamped to the optimal cutting and suturing position of the tissues, the operation incision is reduced, the pain of the patient is relieved, the cross interference of instruments in minimally invasive surgery under an endoscope is avoided, the operation visual field is greatly expanded, the operation time is shortened, and convenience is brought to the operation of a doctor.
The intestinal canal retractor is realized by adopting the following technical scheme:
the intestinal canal retractor comprises a retractor and a retractor handle.
The tractor is provided with a traction rod head, a bending section, a straight rod section and external threads at the tail end of the straight rod section. The head of the traction rod is arc-shaped, which is beneficial to leading the tractor in through a natural channel of a human body and avoids causing tissue damage.
The bending section and the straight rod section of the retractor are cylindrical, the diameter d of the retractor is phi 2 mm-phi 20mm, the included angle α formed by the bending section and the straight rod section is more than or equal to 90 degrees and less than or equal to α and less than or equal to 180 degrees, and a transition arc R is arranged between the bending section and the straight rod section.
The tractor lower part is provided with the terminal external screw thread of straight pole section, and the terminal external screw thread lower part of straight pole section is provided with the chamfer.
The tractor handle is cylindrical, and the diameter D of tractor handle is phi 25mm ~ phi 35mm, accords with the best diameter of holding of staff, and the tractor handle middle part is provided with handle internal thread hole, and handle internal thread hole upper portion is provided with the chamfer, and the tractor handle lower part is provided with convex afterbody.
The tractor is matched with a handle internal thread hole arranged in the middle of a handle of the tractor through external threads at the tail end of the straight rod section and is connected together through threads. The total length of the intestinal canal tractor is 200 mm-800 mm according to the difference of minimally invasive surgical operations under the endoscope.
The tractor is made of aluminum alloy materials.
The retractor handle is made of nylon materials.
The intestinal canal retractor can enter the abdominal cavity of a patient through a natural anal-intestinal channel of a human body in the process of a surgical operation, and can be used for towing, separating and lifting the tissues of the abdominal cavity of the patient, so that the intracavity cutting anastomat can be easily clamped to the optimal tissue cutting and suturing position for carrying out intracavity tissue cutting anastomosis.
The intestinal canal retractor is reasonable in design, compact in structure, simple and practical, and the retractor handle are adopted to draw, separate and lift tissues at the abdominal cavity part of a patient, so that an intracavity cutting anastomat is easily clamped to the optimal tissue cutting and suturing position, surgical incisions are reduced, the pain of the patient is relieved, the cross interference of instruments during minimally invasive surgery under an endoscope is avoided, the surgical visual field is greatly expanded, the surgical time is shortened, and convenience is brought to the surgical operation of doctors.
