Description

Storage device and circumcision device

Technical Field

The present invention relates to a surgical medical instrument, and more particularly to a circumcision apparatus for cutting an excessively long foreskin of a male penis, and a storage device for the circumcision apparatus.

Background

Prepuce overlength or phimosis is one of the sources of urinary infections and sexually transmitted diseases in men. The chronic prostatitis caused by the urethra infection due to the overlong prepuce or phimosis can cause a series of symptoms such as waist soreness, back pain, impotence and premature ejaculation, so that the clearing of the overlong prepuce is one of the good measures for preventing the diseases.

Traditionally, phimosis or overlong foreskin is removed by adopting a surgical operation mode, and the technical points are that redundant foreskin is cut off, hemostasis is performed, and incisal edge skin is aligned and sutured. The postoperative patient can not walk, the pain is hard to endure every time the medicine is changed, the patient also needs to endure huge pain when the stitches are finally removed, and in addition, the foreskin hematoma is caused by incomplete ligation and hemostasis, and the operation treatment needs to be performed again.

Detailed Description

For convenience of understanding, in this document, for example, taking the circumcision instrument 100 shown in fig. 1 as an example, the end of the circumcision instrument and its various components close to the human body during the circumcision operation (e.g., the left end of fig. 1) is referred to as the distal end, and the end of the circumcision instrument and its various components away from the human body or close to the operation of the operator (e.g., the right end of fig. 1) is referred to as the proximal end.

Furthermore, in the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in schematic form in order to simplify the drawing.

Figures 1-13 illustrate a circumcision apparatus 100 according to a first embodiment of the present invention. Referring to fig. 3, the circumcision apparatus 100 of the present invention for removing an overlong foreskin or phimosis of a male patient includes a positioning device 11 configured to position the glans and foreskin of the human body.

Referring to fig. 1, 4, 5, 6A and 6B, the positioning device 11 includes a positioning cylinder 111 configured to fit over the glans of a human body (not shown), a support surface 112 and an annular, flexible first protective film 113. A support surface 112 is formed on the end surface of the proximal end of the positioning cylinder 111 and projects radially outward, and a glans portion is inserted into the positioning cylinder 112, and the excised foreskin is turned over and supported on the support surface 112 and continues to extend distally. A plurality of molding grooves 1121 are formed on the support surface 112, and the plurality of molding grooves 1121 are annularly arranged on the support surface 112. The first protection film 113 in a ring shape covers the molding groove 1121.

In a further embodiment, the circumcisor 100 further comprises an actuating means 12 and a drive means 13. The actuating means 12 comprises a body frame, ligation means and resection means. The positioning device 11 is mounted on the main body frame. The molding groove 1121 cooperates with the ligation device to tighten the ligation member to the corresponding blood vessel. The ligation device is mounted on the body frame and includes a storage device 14 for storing a plurality of binding members (not shown) and a first actuating mechanism for driving the plurality of binding members to respectively bind the plurality of blood vessels on the positioned foreskin, and a second protective film 145 for buffering the binding members is provided on the storage device 14. The cutting means is mounted on the main body frame and includes an annular cutter 16. A drive means 13 is mounted on the body frame and is configured to drive the ligation device and the excising device to move within the body frame such that the ligation device drives the tie member to tighten the blood vessel and subsequently causes the circular cutter 16 of the excising device to excise a foreskin (not shown) including the tightened blood vessel.

According to the circumcision apparatus 100 of the present invention, a fastening member like a staple is first fastened to a blood vessel in the foreskin using a ligation apparatus, and then an excessively long foreskin is cut off using the ring-shaped cutter 16 of the cutting apparatus while the foreskin including the fastened blood vessel remains on the human body. Therefore, the blood loss can be reduced, the possibility of genital infection is reduced, and the pain of male patients is relieved. The fastening piece fixed on the blood vessel can automatically fall off along with the healing of the wound, and no additional operation is needed. Since the annular first protection film 113 covers the forming groove 1121, the first protection film 113 can form a buffering function between the tightening member and the foreskin, and can promote the automatic falling off of the tightening member after healing, thereby relieving pain of a patient caused by incomplete falling off of the tightening member.

In an exemplary embodiment, the angle between the support surface 112 and the axis of the positioning cylinder 111 is acute, thus conforming to the shape of the glans penis for facilitating cutting of the foreskin. In an exemplary embodiment, the angle is in the range of 30-60 degrees.

An annular gasket 1122 is provided on the support surface 112, the annular gasket 1122 being provided on one side of the forming groove 1121. An annular gasket 1122 may be provided in an annular groove formed on the support surface 112 for cooperation with an annular cutter for severing the foreskin. The annular cushion 1122 is made of, for example, a rubber material to reduce pain to the patient.

A plurality of markings 1123 are formed on the support surface 112, each marking 1123 being aligned in a radial direction with a respective shaped groove 1121. In an exemplary embodiment, the identification 1123 comprises a plurality of depressions or protrusions formed on the outer edge extending perpendicularly from the outer edge of the support surface. Each recess or projection is aligned in a radial direction with a respective shaped groove 1121. With this arrangement, the forming groove 1121 will be covered when the wrapper is flipped over onto the support surface 112. The operator can observe the blood vessel and feel the mark 1123 before cutting the overlong foreskin, align the blood vessel with the forming groove 1121 and the tightening member by aligning the blood vessel with the mark recess, and position the foreskin and the blood vessel thereof, thereby accurately fixing the tightening member to the blood vessel.

Further, the positioning device 11 further comprises a clamping band 114, said clamping band 114 being arranged at the periphery of the positioning cylinder 111 to clamp the foreskin passing over the support surface 112 to the outside of the positioning cylinder 111. More specifically, as shown in fig. 6A, an annular groove 1111 is formed on the positioning cylinder 111, and the clamping band 114 can clamp the jacket into the annular groove 1111 in axial movement with the clamping-free band 114. The fastener strip 114 is provided with a plurality of ratchet teeth that allow the fastener strip 114 to be clamped in one direction. In this way, the fastener strip 114 can be progressively clamped as desired, and the fastener strip 114 can be secured in a clamped position. After the procedure is completed, the fastener strip 114 may be removed by cutting.

Referring to fig. 2A, 2B, 7A, 7B, 8A and 8B, the main body frame includes: a main body cylinder 121 and an inner cylinder 123.

More specifically, referring to FIGS. 8A, 9A-9C, the storage device 14 includes a storage ring 141 mounted on the outside of the distal end of the inner barrel 123 and a plurality of storage holes 143. Storage holes 143 are formed on the storage ring 141 outside the outer wall of the inner cylinder 123 in the radial direction (i.e., away from the outer wall of the inner cylinder 123 by a predetermined distance in the radial direction), and the binding members are stored in the storage holes 143, respectively. The storage ring 141 is provided with a flexible second protective film 145 (fig. 7B) for covering the storage hole. Due to the flexibility, the tightening member protruding out of the storage hole 143 can be buffered, so that the speed of the tightening member is increased after piercing the second protection film 145, thereby more smoothly piercing the foreskin of the human body and alleviating pain of the patient.

Referring to fig. 2B, 8B and 10, the first actuating mechanism includes: a first annular support frame 15 movably disposed in the actuation space 124; a plurality of driving arms 151 mounted on a distal end of the first ring support frame 15 and configured to drive the tightening members stored in the storage holes 143; and a plurality of first driving posts 152 mounted on the proximal end of the first annular support frame 15 and protruding from the proximal end surface of the connecting portion 125 through respective first through holes 1251 formed on the connecting portion 125. Referring to fig. 8A, 9A-9C, the storage device 14 further includes a skirt 142 and a plurality of retainers 144. Skirt 142 extends proximally from storage ring 141 outside of inner barrel 123.
