Abstract
The invention relates to a medical appliance, in particular to a bending type laparoscopic surgery appliance, which mainly comprises a connecting pipe, a fixed handle, a movable handle, a pull rod adjusting device and an operating head, and is characterized in that the middle part of the connecting pipe is bent, the front part and the rear part of the connecting pipe are positioned on the same straight line, and the fixed handle and the connecting pipe are generally hinged.
Description
Technical field:
The present invention relates to medical apparatus and instruments, the surgical instrument of bending laparoscope that uses in specifically a kind of clinical operation.
Background technology:
As everyone knows, Minimally Invasive Surgery is because wound is little, treatment time is short, advantages such as patient's pain is light and being used widely, Minimally Invasive Surgery is to adopt puncture needle that human body is punctured earlier, then laparoscopic cannula is inserted in the human body, as connecting in the human body and external passage, the doctor can be sent into peritoneoscope and diagnose the state of an illness in the human body by laparoscopic cannula, the doctor can stretch into other abdominal operation apparatus in the human body by laparoscopic cannula simultaneously, the patient is treated, existing Minimally Invasive Surgery apparatus all is rigid straight-bar type, mainly by connection tube, fixed handle, flexible handle, pull bar, operating head is formed, pass through operating grip, operating head can be realized the needed action of doctor, connection tube wherein is that a straight tube also claims the apparatus body, the connection tube front end is provided with operating head, the rear end is provided with handle, be provided with the operation pull bar in the pipe, because connection tube is a straight tube, it can only carry out linear operating, the relative connection tube of fixed handle is not rotatable, in some operation a plurality of laparoscopic cannulas only is set on human body and just can finishes operation.
Summary of the invention:
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of bending-type, the rotating rigid laparoscopic procedure operating theater instruments of the relative connection tube of handle.
The present invention can reach by following measure:
A kind of surgical instrument of bending laparoscope mainly comprises connection tube, fixed handle, flexible handle, pull bar, pull bar adjusting device and operating head, it is characterized in that the connection tube middle part is bending, and the connection tube front and rear is on same straight line.
Fixed handle and connection tube flexibly connect among the present invention, and general the employing is hinged, so that the relative connection tube of operating grip can be rotated, suitable operation needs.
The present invention is owing to adopt forniciform connection tube, make apparatus can walk around some organ and carry out linear operating, have novel, simple in structure, easy to operate, reliable operation, simplification operation technique, reduce surgical staff, reduce operating theater instruments, reduce the operation cost and can reduce advantage such as patient's operative incision.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
The specific embodiment:
Below in conjunction with accompanying drawing the present invention is further described:
As shown in drawings, a kind of surgical instrument of bending laparoscope, mainly comprise connection tube 1, fixed handle 2, flexible handle 3, pull bar 4, pull bar adjusting device and operating head 5, connection tube 1, fixed handle 2, flexible handle 3, pull bar 4, the structure of pull bar adjusting device and operating head 5 is same as the prior art, this does not give unnecessary details, connection tube 1 middle part is bending among the present invention, the front and rear that is the connection tube 1 after bending is on same straight line, that is to say that operating head 5 and handle are on same straight line, fixed handle 2 adopts with connection tube 1 and flexibly connects among the present invention, the general employing is hinged, so that the relative connection tube of operating grip can be rotated, suitable operation needs, interlude of the present invention can adopt the mechanical bend mode to carry out bending, also can adopt memorial alloy to make a pipe joint body section 6 at the pars intermedia of connection tube, generally be provided with three joints, the body section 6 that memorial alloy is made can become bending by linearity with variation of temperature, enlarge the exploration scope of connection tube front end union joint, operation with suitable diverse location needs, make apparatus can walk around some organ and carry out linear operating, the connection tube 1 leading section bending that appearance needs in that a few joint memorial alloy body sections 6 distortion are back, enlarge the exploration scope of connection tube front end union joint, operation with suitable diverse location needs, before the present invention inserts human body, the connection tube front end is direct rod shape, when inserting human body, rising with the connecting rod temperature, the connection tube leading section curves predefined bending automatically, make operating head carry out patient's lesion easily, when operation finishes, when extracting connection tube out, connection tube reduction of temperature when extracting out becomes direct rod shape, leave human body easily, because the relative connection tube of handle can relatively rotate, make things convenient for operation technique, improve surgical effect, have novel, simple in structure, easy to operate, reliable operation, simplify operation technique, reduce surgical staff, reduce operating theater instruments, reduce the operation cost, and can reduce advantages such as patient's operative incision.
