[0001] The invention relates to the technical field of operating tables, and in particular to a rectal cancer operating table which is beneficial to improving spatial exposure. Background Art

[0002] Rectal cancer surgery is a complex and delicate surgical procedure that requires doctors to perform delicate operations within a limited field of view and operating space. During traditional rectal cancer surgery, patients are usually in a lying position, which to a certain extent limits the doctor's access to the patient's anal area and the operating space. Especially when surgery is required for low-lying rectal cancer, due to the special anatomical position of the rectum and anus, the surgical field of view and operating space are often narrow, which increases the difficulty and risk of the operation. Therefore, it is necessary to design a rectal cancer operating table that can improve the surgical field of view and operating space to improve the success rate and safety of the operation.

The operation is simple and convenient.

[0036] Furthermore, the support plate 211 is in the shape of a long plate and a bracket 2111 is provided on the midline of the length direction of its top surface. The bracket 2111 is a concave arc surface and runs through the rear end of the support plate 211, and is used to stably and comfortably support the calf; a rotating shaft 2112 with an I-shaped cross-section is provided in the middle of the front end of the support plate 211, and the support plate 211 and the rotating shaft 2112 are injection molded into an integral structure using PP material, a through hole is provided on the side wall of the support sleeve 212 and a pin is inserted in the through hole, and the inner end of the pin extends to the annular groove provided on the side wall of the rotating shaft 2112, so that the support plate 211 and the support sleeve 212 can rotate freely without slipping.

[0037] Specifically, Fig.10 As shown, one side of the slot 2122 is a right-angled surface, and the other side thereof is an upward inclined surface. The upward edges of both ends of the limiting rod 213 are provided with inclined sliding surfaces 2132, and the inclined sliding surfaces 2132 are slidably connected with the upward inclined surfaces; so that when the support sleeve 212 and the sliding tube 221 are rotated to expand the angle, the upward inclined surface of the slot 2122 and the inclined sliding surface 2132 of the limiting rod 213 slide and push, and the limiting rod 213 is automatically pushed open, so that the support plate 211 is quickly adjusted to expand and support the calf; and the calf When the support plate 211 is pressed down, the right-angled surface of the slot 2122 will be locked with the right-angled surface of the limiting rod 213 to form a limited state; the side walls at both ends of the limiting rod 213 are provided with grooves 2131 corresponding to the two bosses 2211, and the compression spring 214 is placed between the bosses 2211 and the inner ends of the groove 2131 close to the two ends of the limiting rod 213; the downward rotation movement of the support plate 211 relative to the sliding tube 221 can be adjusted by pulling the limiting rod 213 back to disengage the slot 2122.

[0038] Furthermore, the left and right side walls of the support plate 211 are symmetrically provided with slide grooves 2113, the inner width of the slide groove 2113 is greater than the width of its outer port, thereby forming a limiting structure, and the slide groove 2113 runs through the rear end of the support plate 211, the strap 215 is made of an elastic band and a Velcro is sewn on its upper end so that the two straps 215 can pass over the top of the small support and be bonded and fixed; the lower end of the strap 215 is sleeved with a sliding sleeve 216, and the side wall of the sliding sleeve 216 is provided with a slider 2161 that is slidably engaged with the slide groove 2113, so that the strap 215 can flexibly adjust the binding position; the bottom end of the strap 215 is bonded with a clamping strip 2151 that is engaged with the bottom port of the sliding sleeve 216, so that the lower end of the strap 215 is limited and the calf is tightened and bound to the support plate 211.

[0039] Specifically, Fig.12 and Fig.13 As shown, the two side walls at the lower end of the sliding tube 221 are symmetrically provided with insertion holes 2212 plugged with the positioning block 231, and the side walls of the supporting rod 222 are annularly provided with a plurality of through grooves 2221 at equal intervals. When the sliding tube 221 and the supporting rod 222 are slidably expanded or retracted, each through groove 2221 can correspond to and coincide with a pair of insertion holes 2212 and the size is adapted, and the positioning block 231 is correspondingly plugged with the insertion hole 2212 and the through groove 2221 in turn, thereby positioning the height of the sliding tube 221 and the supporting rod 222 to support the support plate 211; An inverted L-shaped linkage rod 2311 is vertically provided on the outer side of the upper end of the positioning block 231.
