Specific embodiment

It is new below in conjunction with this practicality to make purpose, technical scheme and the advantage of the utility model embodiment clearer Accompanying drawing in type embodiment, is clearly and completely described, it is clear that retouched to the technical scheme in the utility model embodiment The embodiment stated is a part of embodiment of the utility model, rather than the embodiment of whole.Based on the enforcement in the utility model Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made is belonged to The scope of the utility model protection.

Referring to shown in Fig. 1,2, the muscle pull device of general surgery described in the utility model embodiment；Carve on underframe 2 There is graduation mark 1, and chute 3 is opened up on underframe 2, and a matched slide block 4 is set in chute 3.

One end of one end connection expansion link 5 of arched arm 10, and connect moving tooth 11 below the other end of arched arm 10, with This constitutes a support arm, and this support arm is fixed on underframe 2, then is symmetrical arranged a support arm, and is fixed in cunning On block 4, and a spring 6 is set between the expansion link 5 of two support arms, a steel wire is connected on the support arm on slide block 4 Rope 7.

Referring to shown in Fig. 1,2,3,3 gears 901 are from left to right set gradually in the same horizontal line in housing 906, and And the leftmost radius of gear 901, more than the middle radius of gear 901, the radius of idler gear 901 is more than rightmost gear 901 radiuses.A rotating shaft 902 is fixedly connected on leftmost gear 901, and the other end of steel wire rope 7 is connected to into rotating shaft On 902.A connecting rod 903 is fixedly connected on rightmost gear 901, the upper end of connecting rod 903 passes through housing 906, and passes through Rotating disk 904, and rotating disk 904 is fixedly connected on connecting rod 903.The top of connecting rod 903 is bolt structure, and the top of rotating disk 904 sets Put a nut 905 being adapted with stud.

During using this device, first pass through rotation rotating disk 904 and drive rotating shaft 902 to pack up on steel wire rope 7, so as to slide block 4 drives Support arm is close to fixed support arm；According to the needs of operation during operation, rotating disk 904 is adjusted, steel wire rope 7 is slowly put in beginning, Support arm on slide block 4 is backed down laterally in the presence of spring 6, when top to operation needs apart from when, can be in graduation mark See well on 1.The radius of 3 gears 901 is sequentially reduced into reason to be because, no matter when rotating rotating disk 904 how soon, Under the gear drive that 3 radiuses are sequentially reduced, the rotating speed of rotating shaft 902 can be very slow, such that it is able to avoid dynamics mistake well When big, the damage for causing is retracted to muscle.After the distance of requirement is reached, by the way that nut 905 is tightened so as to rotating disk 904 be pressed On housing 906, so as to play fixation.

Lighting device 9 is set, clearer in operation can be performed the operation, stand-by power supply is to work as powering-off state occur Under can be with standby.

It should be noted that herein, such as first and second or the like relational terms are used merely to a reality Body or operation make a distinction with another entity or operation, and not necessarily require or imply these entities or deposit between operating In any this actual relation or order.And, term " including ", "comprising" or its any other variant are intended to Nonexcludability is included, so that a series of process, method, article or equipment including key elements not only will including those Element, but also including other key elements being not expressly set out, or also include for this process, method, article or equipment Intrinsic key element.In the absence of more restrictions, the key element for being limited by sentence "including a ...", it is not excluded that Also there is other identical element in process, method, article or equipment including the key element.
