Description
Technical field
This utility model belongs to technical field of medical equipment, particularly a kind of improvement Valdivia position PCN surgical stent.
Background technology
Percutaneous nephrolithotomy (percutaneousnephrolithotomy, PCNL) is the prefered method for the treatment of complex renal calculi and proximal ureteral calculus.At present at home and abroad, during clinical up PCNL, patient adopts ventricumbent position usually.This position penetrating area is broad, and apparatus activity space is comparatively large, and puncture success rate is higher, but also there is a lot of shortcoming.This is because during ventricumbent position, patient chest abdomen pressurized, does not feel like oneself, easily cause hemodynamic change, particularly for fat, old and cardio-pulmonary function obstacle person, more easily cause the complication of breathing and blood circulation, and rescue in the unfavorable Rhizoma Atractylodis Macrocephalae of this position, there is high risk.In addition, when adopting this position, in art, patient first adopts calculi position, after change ventricumbent position into, then change horizontal position into, 2 positions need be converted, add the risk of unexpected injury.For this reason, scholar is constantly had to explore other treatment position both at home and abroad.
Since first nineteen ninety Valdivia proposes dorsal position PCN technology, Chinese scholars successively reports multiple PCNL and treats position, as anti-calculi position, lateral position, dorsal position (Valdivia position), tiltedly dorsal position, tiltedly to lie on the back calculi position (improvement Valdivia position) etc., wherein improveing Valdivia position applies comparatively wide in recent years, has higher rating.Improvement Valdivia position combines oblique dorsal position and calculi position 2 kinds of positions, and patient Shu Zhong face and thorax abdomen, therefore fundamentally avoid a series of complication and untoward reaction brought ventricumbent position upward.Clinical practice proves, improvement Valdivia position is safe and effective, is particularly suitable for the high-risk patients such as obesity, old and cardio-pulmonary function obstacle.
Improvement Valdivia position: patient tiltedly lies on the back, and Ipsilateral body becomes 20 ° ~ 30 ° angles with bed plane, upper limb hangs on front.Two lower limbs are separately placed in leg support, and Ipsilateral is slightly low, and offside is abduction slightly.For this operation position, still there is no special surgical stent clinically at present, but need with cushion or bag of saline Ipsilateral thoracic dorsal and buttocks padded, then put a cushion in offside waist side of body portion, push abdominal part to Ipsilateral.Such adjustment position complicated operation, inaccuracy, and add the risk in operation process.
Summary of the invention
The purpose of this utility model is the PCN surgical stent providing a kind of easy to operate, safe and reliable improvement Valdivia position.
The technical solution realizing this utility model object is: a kind of PCN surgical stent improveing Valdivia position, comprise base, gripper shoe, baffle plate and angle regulator, base is a rectangular flat, one end of gripper shoe is connected with base by hinge, the other end is that free end can rotate around hinge, the free end side mid portion of gripper shoe offers space, makes gripper shoe be concave shape; Be provided with angle regulator between the bottom of gripper shoe and base, angle regulator, by raising the free end of gripper shoe, adjusts the angle between gripper shoe and base; Baffle plate is installed in the guide rail of submounts, and guide rail is perpendicular to the hinge of gripper shoe, and the chain connection of guide rail one end and gripper shoe, the other end extend to the edge of base; Baffle plate along slide, can be fixed by the baffle plate after position adjusts by alignment pin.
Preferably, described angle regulator is hydraulic regulating device.
Preferably, described angle regulator can regulate and make the angle between gripper shoe and base be 20 ° ~ 30 °.
Preferably, gripper shoe is divided into three sections by the space in the middle of described concave shape gripper shoe, and two sections of two ends are respectively used to raise patient chest and buttocks, and intermediate gaps section makes Ipsilateral waist unsettled.
Preferably, the quantity of described angle regulator is 2, and is distributed in the both sides of gripper shoe intermediate gaps part.
Preferably, the quantity of described guide rail is 2, each one of the two ends of baffle plate.
Preferably, the quantity of described alignment pin is 4, and four angles bottom baffle plate are respectively fixed by an alignment pin 4.
Preferably, the height of described baffle plate is greater than 25cm.
Compared with prior art, its remarkable advantage is this utility model: (1) for improvement Valdivia position, can determine the position of patient specially quickly and easily; (2) position adjustment can be carried out conveniently by support, instead of frequently move patient, thus reduce the risk of patient's unexpected injury; (3) whole supporting structure is simple and cheap, has safe and reliable, easy to operate advantage.

Fig. 2 is the top view of the PCN surgical stent of this utility model improvement Valdivia position.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further details.
Composition graphs 1 ~ 2, the PCN surgical stent of this utility model improvement Valdivia position, comprise base 1, gripper shoe 2, baffle plate 3 and angle regulator 5, base 1 is a rectangular flat, one end of gripper shoe 2 is connected with base 1 by hinge, the other end is that free end can rotate around hinge, the free end side mid portion of gripper shoe 2 offers space, makes gripper shoe 2 in concave shape; Be provided with angle regulator 5 between the bottom of gripper shoe 2 and base 1, angle regulator 5, by raising the free end of gripper shoe 2, adjusts the angle between gripper shoe 2 and base 1; Baffle plate 3 is installed in the guide rail 6 above base 1, and guide rail 6 is perpendicular to the hinge of gripper shoe 2, and the chain connection of guide rail 6 one end and gripper shoe 2, the other end extend to the edge of base 1; Baffle plate 3 can slide along guide rail 6, is fixed by the baffle plate 3 after position adjusts by alignment pin 4.
The PCN surgical stent of this utility model improvement Valdivia position can be fixed on current operation table, and easy to loading and unloading, use procedure is as follows: during operation, and patient lies in gripper shoe 2, and baffle plate 3 ensures that patient can not glide; Two sections of gripper shoe 2 two ends are respectively used to raise patient chest and buttocks, and intermediate gaps section makes Ipsilateral waist unsettled, expand puncture space; According to operation needs, employing angle regulator 5 adjusts the angle between gripper shoe 2 and base 1, is convenient to operation technique; Baffle plate 3 slides along guide rail 6, for passing to offside, allows patient's abdominal part shift to offside as far as possible, and fixing Ipsilateral kidney also makes skin kidney distance shorten as far as possible, thus reduces venipuncture difficulty.
As preferably, described angle regulator 5 is hydraulic regulating device, also can select the adjusting device of other structure as required.
As preferably, described angle regulator 5 can regulate and make the angle between gripper shoe 2 and base 1 be 20 ° ~ 30 °.Be convenient to operation technique when angle between gripper shoe 2 and base 1 is 20 ° ~ 30 °, as elevation angle is greater than 300, although it is more convenient to puncture, takes calculi position difficulty, and be unfavorable for that x-ray is located; As being less than 20 °, then puncture limited space, and can increase the risk of intestinal injury.
As preferably, gripper shoe is divided into three sections by the space in the middle of described concave shape gripper shoe 2, and two sections of two ends are respectively used to raise patient chest and buttocks, and intermediate gaps section makes Ipsilateral waist unsettled, expands puncture space.
