Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Below in conjunction with drawings and Examples this utility model is further described.

As shown in Figure 1.

A kind of laparoscopic surgery liver retractor, except that wearing piece, all adopt the stainless steel material manufacturing, comprise the base 1 that is installed on the operation table, base 1 can be a straight-bar, it also can be knee, concrete structure should be decided according to the characteristics and the locking mode of operation table, shown in Fig. 1 is the structure that the upper end is the knee shape, crossbeam 2 is installed on the base 1, and base 1 can be a monolithic construction with crossbeam 2, also can be the split part, when adopting split part shown in Figure 1, the upper end of base 1 should be provided with the screw rod 18 that passes the unthreaded hole on the crossbeam 2, and crossbeam 2 is fixed on the base 1 by the locking nut 19 of the band handle that matches with screw rod 18, when dividing body structure, after base 1 is fixed, can realize different angle orientation by adjusting crossbeam 2.The combination of base 1 and crossbeam 2 is equivalent to people's health.Shoulder ball rod 3 is installed on one end of crossbeam 2, the bulb 4 of shoulder ball rod 3 is installed in the shoulder ball-and-socket 5 (shoulder that is equivalent to human body), shoulder ball-and-socket 5 links to each other with an end of last armed lever 6, in the shoulder ball-and-socket 5 spring 20 and wearing piece 21 (can adopt nonpoisonous and tasteless politef) are installed, one end of spring 20 offsets with the bottom of shoulder ball-and-socket 5, the other end and wearing piece 21 offset, wearing piece 21 contacts with bulb 4, has the breach 22 that shoulder ball rod 3 can be entered in shoulder ball-and-socket 5 and bulb 4 corresponding positions.The other end of last armed lever 6 (being equivalent to the upper arm of the shoulder of human body to ancon) is connected with rotor 7, last rotor 7 is sleeved on the upper end of rotor pin 8, the lower end of rotor pin 8 is fixed on down on the rotor 9, last rotor 7 and following rotor 9 are by rotor pin 8 and locking member 10 locking positionings, last rotor 7 and following rotor 9 are connected to form the structure of the elbow joint that is similar to the people by rotor pin 8 and locking member 10 (the general nut that has handle that adopts), it can be in horizontal plane any rotational positioning; Following rotor 9 is installed on support bar 11 end of (being equivalent to the human body ancon to the underarm part between the wrist), the other end of support bar 11 is equipped with wrist ball-and-socket 12, the bulb 14 of wrist ball rod 13 1 ends is installed in the described wrist ball-and-socket 12, wrist ball-and-socket 12 and wrist ball rod 13 are equivalent to the wrist part of human body, and space angle rotates arbitrarily.Spring 23 and wearing piece 24 (also can adopt nonpoisonous and tasteless politef) are installed in the wrist ball-and-socket 12, one end of spring 23 and the bottom of wrist ball-and-socket 12 offset, the other end and wearing piece 24 offset, wearing piece 24 contacts with bulb 14, has the breach that the shank portion that makes wrist ball rod 13 can enter in wrist ball-and-socket 12 and bulb 14 corresponding positions.The other end of wrist ball rod 13 links to each other with yaw 15, and yaw 15 is provided with the jack 16 that is used for plug-in mounting hook (finger that is equivalent to the people), with the perpendicular direction of described jack 16 axis on the locking member 17 that is used to lock hook is installed.During concrete enforcement, wrist ball rod 13 also can adopt integral structure component with yaw 15, can utilize the screw rod (being locking member 17) of being with handle to be pressed in behind the upper end insertion jack 16 of hook and make it on the hook to be fixed in the jack of yaw, can't extract.The shape of hook generally by the straight bar part that is used for inserting plug with vertical with straight bar part or be similar to the vertical crotch plane body that is used to hold up liver and form.

Using method of the present utility model is:

At first base 1 is fixed on the bed frame of operation table, is sleeved on crossbeam 2 on the base 1 then and the latch fitting spare 19 but do not tighten screwed on, unclamp locking member 10 to enable in horizontal plane, the regulating angle of revolution; Then the planar ends of being made up of knee of hook is inserted in the human body from the hole of accomplishing fluently in advance, and under laparoscopically guide, liver is placed on the hook, then hook is exposed the outer end of human body and insert in the jack 16 on the yaw and tighten locking member 17.The angle of pulling bulb 4 and bulb 14 at last respectively and going up rotor and following rotor makes whole retractor be in one not only to be convenient to the position of performing the operation but also liver can be mentioned, and to have tightened locking member 10 at last and can begin to perform the operation.In the operation process as need to adjust among a small circle directly to pull bulb, carry out big adjustment as need and can unclamp earlier and tighten locking member 7 again after locking member 7 makes rotor and following rotor forward suitable position to.

This utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
