Description

The stomach wall lifter

This utility model relates to a kind of medical apparatus of the usefulness of performing the operation, and is meant that especially enlarging the space, abdominal cavity implements the medical apparatus that laparoscopic surgery is used.

Using laparoscopic surgery at present is to implement CO ₂Pneumoperitoneum forms expansion space, abdominal cavity and finishes operation, and the abdominal cavity is at CO in the whole surgery process ₂Atmospheric pressure be the high pressure conditions of 12-15mmHg, the patient is caused many harm, diaphram is raised, vital capacity reduces, abdominal wall blood vessel pressurized causes breath cycle load to increase, and seriously disturbs the patient respiratory circulatory function; By CO ₂The formed pneumoperitoneum of gas also may produce vertical diaphragm, thoracic cavity and subcutaneous emphysema; CO ₂Can absorb by peritoneum, produce hypercapnia, cause the interior environment disorder of patient's body.Simultaneously, pneumoperitoneum is essential with expensive pneumoperitoneum apparatus and highly purified CO ₂Gas, and pneumoperitoneum must adopt under the general anesthesia and undergo surgery, and can't implement pneumoperitoneum to the patient that the general anesthesia contraindication is arranged, and these conditions have all limited the range of application of laparoscopic surgery.

The novel purpose of this reality is to design a kind of utensil, adopts the mechanical stretch mode to make stomach wall promote expansion, forms the operation technique space, avoids implementing CO ₂Pneumoperitoneum does not need pneumoperitoneum apparatus and high-purity CO to many harm that patient causes ₂Just can implement laparoscopic surgery, also not need patient is applied general anaesthetic, not be subjected to the restriction of these conditions, therefore enlarge the range of application of laparoscopic surgery.And can be hospital and patient reduces medical expense.

Technical solution of the present utility model is a kind of abdominal cavity lifter, supporting folder by the connection of mounting bracket mat Connection Block constitutes, supporting folder is constituted by two Z type clamping bars, every curved respectively flat intermediate plate and the clamp holder of analysing in Z type clamping bar two ends, intermediate plate and clamp holder be not in same plane, a Space Angle mutually staggers, the parallel hinge of middle straight line segment of two Z type clamping bars is linked together, connect firmly horizontal connecting rod, connecting rod end has the length direction of a wedge shape dovetail shaped double wedge, double wedge to be wedge shape, long-pending the varying in size of the long two ends of tooth dovetail shaped cross sections; Mounting bracket is that a vertical and horizontal is stretched all flexible adjustable support of distance; Connection Block is that mat wedge shape dovetail shaped tooth, groove grafting connect with supporting connecting of folder.

Description of drawings is as follows:

Fig. 1 is a used for medical procedures stomach wall lifter structural representation

Fig. 2 is mounting bracket partial structurtes sketch maps

Fig. 3 is Connection Block and supports folder mat wedge shape dovetail shaped tooth, groove grafting draw bail sketch map

This utility model further specifies as follows in conjunction with specific embodiments referring to accompanying drawing:

A kind of stomach wall lifter supports folder [3] by mounting bracket [1] mat Connection Block [2] connection and constitutes.Referring to accompanying drawing 1, supporting folder [3] is constituted by two Z type clamping bars [5]: every Z type clamping bar [5] two ends are bent into flat intermediate plate [6] and clamp holder [4] respectively, intermediate plate [6] and clamp holder [4] be not in same plane, a Space Angle mutually staggers, the parallel hinge of middle straight line segment of two clamping bars is linked together, connect firmly horizontal connecting rod [7], laterally connecting rod [7] end has a wedge shape dovetail shaped double wedge [8], referring to accompanying drawing 2, the length direction of double wedge [8] is a wedge shape, and the dovetail shaped cross sections at the long two ends of tooth is long-pending to vary in size.

Mounting bracket [1] is that a vertical and horizontal is stretched all flexible adjustable support of distance.It goes up dress vertical lift bar [10] by bearing [9], and bar [10] top is adorned horizontal expansion link [12] and constituted.The concentric pipe that horizontal expansion link [12] is varied in size by overloading sliding sleeve successively connects and constitutes, bar [12] one ends laterally have a through hole, there is a bolt on bar [10] top along axis, and bar [12] end cross through hole is sleeved on the vertical bolt of bar [10], and mat nut [11] presses solidly tightly.Bar [12] other end hinge connects Connection Block [2]; Wedge shape dovetail shaped open slot [13] is arranged, referring to accompanying drawing 2 on the Connection Block [2].Groove [13] is wedge shape along its length, and the section of length two ends dovetail groove is long-pending to vary in size, and the small end sealing.

Rectangular aperture mounting groove [17] is arranged on the bearing [9], referring to accompanying drawing 3, there are installation trip bolt [18], vertical lift bar [10] to connect on groove [17] sidewall and constitute vertical rod by the concentric pipe sliding sleeve of the overloading that varies in size, bar [10] slip cap is loaded in guide [15] on the bearing [9], [16], bar [10] mat worm gear, worm mechanism [20] and turn to bevel gear that [21] are connected with rocking handle [23], rocking handle [23] mat bearing [22] is installed on the bearing [9].Bar [10] stage casing is passed one section of support [9] and is worm screw, with the worm gear engagement of suit on it, constitutes worm-and-wheel gear [20], and the worm gear outer rim is a horizontal bevel gear, constitutes with vertical bevel gear engagement to turn to bevel gear to [21].

When this utility model uses, support [1] is fastened at operating-table one side by bearing [9] mat open slot [17] and screw [18] installation, shaking rocking handle [23] mat turns to bevel gear can make the upper and lower lifting of elevating lever [10] to [21] and worm-and-wheel gear [20], the level of bar [12] adjustable support [1] is stretched distance, slightly loosening vertical lift bar [10] [top clamp nut [11], adjustable lever [12] is a certain angle of beat as required, tightens up nut [11] then and tightens up horizontal expansion link [12]; Hands is pinched the clamp holder [4] that supports folder [3], the then folding of scalable intermediate plate [6], and handle is opened clamping, and handle closes folder and opens.Support folder and stretch in the surgical patient abdomen, can increase the contact area with stomach wall after intermediate plate [6] opens, support expansion stomach wall cavity after folder [3] lifting, broaden one's vision and enlarge the operation technique space for laparoscopic surgery provides.

The utility model has the advantage of simple and compact for structure, flexible practicality, cost is low, is used for promoting stomach wall, enlarges patient's abdominal operation space, need not use CO₂Pneumoperitoneum is avoided causing many because CO to patient₂The harm that pneumoperitoneum brings, and can not be subjected to pneumoperitoneum apparatus, high-purity CO₂And the restriction of general anesthesia condition, enlarge the laparoscopic surgery range of application, also can simultaneously For hospital and patient save medical expense.
