Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, relate in particular to mucosa ring cutting anastomat on a kind of hemorrhoid.
Background technology
Mucosa ring cutting anastomat (PPH) is increasingly extensive in Clinical Application on the hemorrhoid, in use this apparatus also is applied in (a kind of operation method for the treatment of ODS disease) in the STARR operation, but original apparatus inner chamber is big inadequately, the organization department that is received is more than enough, and this will directly cause treatment not enough (under treatment).Doctors have a strong desire, want enough big of the inner chamber of apparatus, tissue can successfully be pulled into inner chamber, because the apparatus bore need be strengthened to obtain the internal diameter of bigger anastomat, because the increase of diameter, a series of problems are just outstanding about strength problem, and tackling this is a brand-new design apparatus, and this just need redesign the structure of apparatus.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide mucosa ring cutting anastomat on a kind of hemorrhoid, make the doctor have an opportunity to use conventional pincers class operating theater instruments effectively to pull into anastomat inner chamber with organizing.
In order to reach above purpose, the technical solution used in the present invention is: mucosa ring cutting anastomat on the hemorrhoid, it comprises shell, arrange in the enclosure and front end stretches out the center-pole of shell, be connected the nail anvil portion of the front end of center-pole, be arranged on the anterior and inner nail bin portion that is provided with some seam nails of shell movably, be connected for promoting the percussion lock that nail bin portion and inseam nail phase nail anvil portion of nail bin portion move with nail bin portion, percussion lock comprises firing handle, it is characterized in that: offer three through holes in the nail bin portion, three through holes distribute around the axial line equal angles of center-pole, and one of them through hole becoming 180 ° perpendicular to the projection on the cross section of the axial line of center-pole around the axial line of center-pole with firing handle, namely on the cross section perpendicular to the center-pole axial line, the position of three through holes is designed respectively at 12 points, 8 points, on 43 positions.The diameter of the front portion of nail bin portion is greater than the diameter at the rear portion of nail bin portion, the rear portion of the front portion of nail bin portion and nail bin portion is connected by the middle part that is funnel shaped nail bin portion, the front portion of each through hole is positioned on the front portion of nail bin portion, and the rear portion of each through hole is positioned on the middle part of nail bin portion.In order to make tissue can enter the inner chamber of nail bin smoothly, must could enter inner chamber to greatest extent with organizing by pulling of apparatus, thus the openings of sizes of through hole to satisfy pincers class operating theater instruments enter back cavity class operating theater instruments by the opening part of through hole can expedite opening.Doctor's operation technique for convenience, through hole that the position is set is very crucial, can make things convenient for the doctor to operate to greatest extent as long as arrange as the position among the application, if operate being inconvenient to 6 positions the position in hole, there is problem in doctor's the visual field in the operation.
Further, nail bin portion comprises cartridge housing, be set in and organize the retaining ring on the center-pole, cartridge housing and organize and be provided with three first reinforcements between the retaining ring, and three first reinforcements arrange at interval with three through holes respectively.In a kind of scheme that is more preferably, every first reinforcement setting and with it the distance between adjacent two through holes equate.The number of first reinforcement of the prior art is four, could guarantee the intensity of nail bin portion like this, owing in nail bin portion, will open three through holes among the application, organize first reinforcement on the retaining ring to make three into by four, its position must be at 10 points, 2 points are located for 6, and namely three first reinforcements are becoming 180 ° perpendicular to the projection on the cross section of the axial line of center-pole around the axial line of center-pole.
Further, the inwall of cartridge housing is provided with many second reinforcements, in a kind of scheme that is more preferably, is provided with second reinforcement about every first reinforcement, and second reinforcement is arranged on the middle part of cartridge housing.Because the increasing of apparatus diameter, the power of apparatus when sewing up cutting will increase and is inevitable, and first reinforcement is reduced to three, considers the strength problem of nail bin portion, must reinforce it, produce bigger strain and influence the molding of seam nail to prevent stressed back.Therefore increase by 6 second reinforcements at the cartridge housing inwall, guarantee the minimal deformation of nail bin portion, reach the best molding purpose of seam nail.
Further, firing handle can be set in impeller on the center-pole movably along described center-pole length direction by one and is connected with nail bin portion and promotes described nail bin portion and move.
The nouns of locality such as related 12 points among the application, 8 points, 4 points, 10 points, 2 points, 6 are to define according to corresponding position of the time on the dial, this dial is positioned on the cross section perpendicular to the center-pole axial line, and wherein the correspondence position of firing handle on this dial is 6 directions.
The related noun of locality such as forward and backward, inside and outside, upper and lower is to do definition at mucosa ring cutting anastomat on the hemorrhoid under the normal state that uses among the application, in operation process, before the direction that anastomat puts in to digestive tract is, after direction in contrast is, in the center-pole position is, outside the shell position was, the firing handle position was for down, in contrast be last.
By adopting technique scheme, mucosa ring cutting anastomat on the hemorrhoid of the present invention adopts the big opening of three-port type, allows the doctor have an opportunity to use conventional pincers class operating theater instruments can effectively pull into inner chamber with organizing by three holes.
